 - [ ] Room server login from the phone app / L1 still works while this exists (only admin logins go to the new session)
 - [ ] L1 (ui-new): Tools > Admin works as before (login, saved password, typed values, confirm reboot); it now also skips the login for the node you just used

+- [ ] Keyboard: the keyboard key (bottom left) closes it; in a chat the typed text stays, in a dialog nothing is saved
+- [ ] Symbols page ("1#"): "_" is in the third row now
+- [ ] Bot > Reply: every placeholder in the row above the field ({name} {hops} {loc} {time} {batt}, sensors); swipe it sideways
+- [ ] WAKE button (side): screen off / on; silences a ringing alarm
+- [ ] USER button: back (answers at once, no double-click wait); held 1 s, sound off / on with a toast and the mute icon; wakes the screen when it's off
+- [ ] Settings > CONNECTIVITY > WiFi: a switch as on Bluetooth (toast, row says "Off" / the network); tapping the row opens the network settings (editable while off; Scan asks to turn it on); off: map download says "WiFi is off"; kept across a reboot
+- [ ] Shorter descriptions on settings rows, Bot, Repeater, Send advert, Bluetooth ("PIN 123456" / "App connected")

 ## New: Quick messages, placeholders, advert, Bluetooth (2026-09-26)
 - [ ] Chat "+" (left of the text field): Insert {loc} / {time} / {batt} (+ sensors) into the message; they are filled in when sent (a reply's "@[name] " stays as typed)
 - [ ] Chat "+" > a quick message sends it at once (the popup shows what will go out, filled in); "Edit quick messages" opens the list

+# Wio Tracker L2 (ui-lvgl) roadmap
+
+The L1 → L2 feature port and its audit are done (2026-09-26). This is the plan
+for what comes next, in order. Tick items off as they land.
+
+Decisions already made:
+
+- **Buttons:** WAKE (side, expander P00) turns the screen off / on. USER/BOOT
+  goes back; holding it mutes / unmutes the device.
+- **Placeholders:** the "+" popup next to a text field is the placeholder UI;
+  it must offer every placeholder and appear at every field that sends text.
+- **Message history:** kept on the SD card, about 100 per conversation to
+  start with.
+- **OTA:** firmware comes from this fork's GitHub Releases.
+- **PIN:** screen lock only, for now.
+
+## 1. Quick fixes
+
+- [x] Keyboard: a key that closes it (so far a message could only be sent).
+- [x] "+" placeholders at every field that sends text (compose, quick
+      messages, bot replies).
+- [x] Short, terse descriptions on buttons and rows.
+- [x] WiFi off switch.
+- [x] Buttons as decided above.
+
+## 2. Arduino-ESP32 3.x, PSRAM
+
+- [ ] A separate L2 env on pioarduino (as `esp32c6_base`); the 2.0.17 env
+      stays until the new one passes the hardware checklist.
+- [ ] Port: speaker (new I2S driver), BLE, ESP-NOW, HTTPS map download,
+      LovyanGFX.
+- [ ] Large buffers in PSRAM: message history, trail, tile cache. Measure
+      internal RAM before / after.
+- [ ] Full hardware checklist, then make the new env the default.
+
+## 3. Data on the SD card
+
+- [ ] Message history on SD, kept across reboots (~100 per conversation;
+      the newest ones cached in PSRAM).
+- [ ] Trail sized to the device: thousands of points in PSRAM (now 512),
+      saved to SD.
+
+## 4. UI layout
+
+- [ ] Every tool as its own Home tile (trail, live share, arrival alert,
+      repeater, admin, diagnostics, ...), not inside Settings.
+- [ ] Settings in a sensible order, as on the original (L1).
+- [ ] Every status icon the original has (BT, GPS, live share, trail,
+      repeater, alarm, mute, arrival alert, ...).
+
+## 5. Security and internet
+
+- [ ] Screen-lock PIN.
+- [ ] Map tiles fetched live while online.
+- [ ] One-button OTA from GitHub Releases (release asset + partition layout
+      check).
+
+## 6. Theme
+
+- [ ] Develop the current look into a consistent, recognisable style
+      (colours, corners, type, icons, states), after the layout of stage 4.
+
+## 7. Research: LVGL for the other displays
+
+- [ ] Find out whether LVGL on every display variant gives consistency and a
+      nicer look more easily. Adopt only if the result is better and every
+      feature is kept (L1: 128×64 OLED, nRF52, RAM already 68% used).
