A cut-paper collage after a picture book about a hungry caterpillar:
the caterpillar is the speed and power, the sun the battery, the story's
fruit the range. The music light bounces the sun and the segments. A
butterfly or a ladybird tows the song on tissue paper.

A tree with a bauble for the speed, fairy lights for the power, a mug of
cocoa for the battery, a wreath clock and candy canes for the range. Its
lights flare on the beat with the music light, now "Light follows the
music" for Halloween and Christmas. A sleigh or an angel tows the song.

NowPlayingWatcher follows the head unit's media sessions (listening
only, never connecting to a player); NowPlaying picks what plays and
cleans the text. Tiles shows source, title, artist, cover and progress
under the battery; Halloween carves title and artist into the hill.
Settings: "Show what's playing", on by default. Nothing is logged or
sent.

MusicPulse reads 40-120 Hz and lights only on jumps of the bass, so
held notes and bass lines stay dark. Settings gets "Pumpkin light
follows the music" (Halloween only, off by default); off, the audio
analyser never starts.

While the style shows its own palette (Sci-fi, Cartoon, Aviation, Nixie;
Retro and Terminal with "Original"), the navigation, buttons and titles
take it instead of the accent colour, e.g. turquoise for Retro
(StylePalette, style_palettes.xml). Blueprint and Mascot are removed; a
stored one opens Tiles. The navigation no longer saves view state, which
crashed a restore across the wide and narrow layouts.

The car falls back to its own default mode at every start. With "Set at
start" (on by default), the service sets the mode last chosen on
Settings and confirmed by the car again, once, while the car is in P at
0 km/h, and gives up as soon as the car leaves P or after two minutes
(DriveModeWrite.atStart, unit-tested). The buttons and the start share
the write and read-back (DriveModeSetter). Not tried on the car.

The owner lifted the read-only rule for the drive mode alone. Settings
has Eco, Normal, Sport, Snow and Custom; the lit button is what the car
reports. A tap reads gear and speed fresh and writes only in P at 0 km/h
(DriveModeWrite, unit-tested; unreadable is a refusal), through a CPM-only
write behind EVHardware's standstill gate, then reads the mode back and
says what the car reports. The wide layout's charging price joined the
battery card so the page still fits. Not tried on the car.

ChibiFigure draws a small, full-figure co-pilot in a hoodie whose whole
body acts the mood (waving, arms up and hopping, fist, hands on cheeks,
nose bubble, pointing back, leaning into the wind). Settings → Mascot
(Classic / Chibi, MascotCharacter) shows only for the Mascot style; the
chibi has lines of her own.

Settings → Display now has the Overview style first with the accent
colour beside it; for styles with their own palette the accent field is
greyed out with a note. Styles are an enum, OverviewStyle, with
usesAccent (unit-tested). Emulator only.

Charging and Consumption get two-column wide layouts; Live data and
Settings are tightened (fields beside their buttons, button rows,
16 dp vertical card padding). Checked on the emulator at 1778x640.

Settings -> App -> "Install from USB stick" (car build only). It looks
in the top folder of every mounted volume (found from the app's own
folder on it, since the head unit has no file picker) for
NilsMG4-unstable-<version>.apk, takes the newest one newer than the
installed version, checks it against its .sha256 sidecar and the
package name, and installs it with the same PackageInstaller session
as the over-the-air update. The stable build gets a stub and no button.
Tested on the emulator: 2.18.0 installed a 2.18.1 from the storage's
top folder without a confirmation, as the system user, so the OTA
install step should not need one either.

- Settings: the Wi-Fi and saved-networks cards are gone, and the rest
sits in three columns (display and steering wheel | battery |
charging price and app) instead of one tall column. The background
Wi-Fi auto-connect stays on, without a switch.
- Logs: only the upload log. The steering-key reports, the car-colour
probe and the screen line answered their questions and are removed,
with their code (CarColorProbe, the key-report log) and strings.
- README lists the current tabs.

- "Speed, 5-min average" card under Speed: time-weighted mean speed,
standing included, from the same samples as the other averages.
- The top bar is one compact line (title and subtitle side by side).
Version, update check and About moved from it to an App card on the
Settings tab.
- The Overview no longer scrolls in the car's window: checked on the
emulator at 1778x640, the layout height the car reports, after
trimming the page's padding and the tyre card's height.
- The capacity hint says "Overview" instead of "Vehicle tab".

Back to drop-downs for upload frequency, tyre pressure unit and accent
colour, as Material exposed dropdown menus instead of Spinners. A
Spinner's list is a focusable window of its own without the
full-screen flags, so the car showed its bars while it was open; an
exposed dropdown's list leaves the focus with the activity, so the app
stays full screen. Styled like the other input fields, with full-height
rows. Replaces the buttons of 2.16.3.

Opening a drop-down or a dialog brought the car's bars back until it
closed: each is a window of its own, and the system shows the bars when
a window without the full-screen flags takes focus.
- The drop-downs (upload frequency, tyre pressure unit, accent colour)
are now single-choice buttons on the page: no extra window, one tap
instead of two, full touch targets, the choice in the accent colour.
- Dialogs (About, update, pairing, phone settings, trip reset, date
picker) are shown unfocusable, given the activity's full-screen
flags, and only then allowed focus. None of them takes typing, which
an unfocusable window would block.

The Charging, Consumption and Settings labels, toasts, the trip-reset
dialog, the charging and Wi-Fi states, the daily summary and the "—"
placeholder move from layouts and code into strings.xml; lint now
reports no hard-coded text. Upload-log entries stay in code, as log
text. No visible change.

The accent is selectable in Settings → Display: Dynamic Red (default),
Volcano Orange, Holborn Blue, Racing Green, Camden Grey, Monument
Silver, Arctic White and Black Pearl. White, silver and black cannot be
an accent on the black screen as they are, so they become light greys
and a pearl blue-grey.
The accent palette is now theme attributes (attrs_accent.xml) with one
overlay per paint (accents.xml), applied before the activity inflates;
layouts, colour lists, drawables and the views that draw in code use
them, including the red tints that were hard-coded. A change recreates
the activity on the same page. Android 9 crashes on gradients with
theme colours, so the battery card is built from layers.
Logs → "Look for the car colour" lists the head unit's system
properties that mention colour, paint or car model, to find out whether
the paint colour can be read from the car.

Tyre pressures show in bar by default; Settings → Display offers kPa
and psi as well. Display only: the car reports kPa and the server keeps
storing kPa.
A "Power, 5-min average" card under Power: the time-weighted mean
battery power over the last five minutes, standing included, from the
same samples as the 5-minute range.

The ABRP credentials are long to type on the car. "Enter on phone"
(Live data tab, and Settings next to the charging price) shows a QR
code; it opens a form on the server where the phone sends the ABRP API
key and user token, charging price and usable capacity, confirmed with
the approval password. The car polls with its own token and collects
the values once, then saves them through the same checks as the fields
on screen.
Same device-flow shape as pairing. The server keeps the values in memory
only, at most ten minutes, hands them out once with no-store, and never
logs them or puts them back into the page; a paired token only reaches
its own installation's request. Pairing's QR dialog is now shared
(PhoneQrDialog), and the phone pages share one stylesheet.
The config file also takes charging_price and usable_kwh.

ABRP keeps getting live data while the car server is down: with an ABRP
API key and user token set in the app (Live data tab, or abrp_api_key /
abrp_token in the config file), the car sends the newest sample to ABRP
itself at every upload. It tells the server the newest sample ABRP took
(abrpSentUtc), and the server forwards only newer ones, so ABRP gets
each sample once. Without credentials in the app the server forwards
everything, as before. The credentials sit in encrypted storage, go in
the request body, and neither they nor ABRP's answer are logged.
Settings are grouped by what they are for:
- Live data (was Upload): on/off, ABRP credentials, upload frequency.
- Settings (replaces the Wi-Fi tab): full screen and voice key,
usable capacity and manual SoH (were on Consumption), charging price
(was on Charging), Wi-Fi.
Charging and Live data get icons of their own.
