The timestamp label was positioned via lv_obj_align_to below the
message box, but the bubble container's LV_SIZE_CONTENT height was
driven entirely by the box, so the time rendered below the bubble's
allocated row in the flex scroll — visibly hanging into the gap.
Add pad_bottom=14 to the bubble so its outer height includes the
timestamp row, and anchor the box at TOP_LEFT/TOP_RIGHT (was
LEFT_MID/RIGHT_MID) so the layout stacks cleanly: box on top,
timestamp tucked under it inside the bubble's bbox.
Regenerated Montserrat 10/12/14 with Cyrillic and Latin Extended
Unicode ranges so messages in Russian, Ukrainian, Bulgarian, and
accented European languages render properly instead of rectangles.
Message view: Extract appendMessage() from rebuildMessages(). New
messages are now incrementally appended (O(delta) widget ops) instead
of destroying and recreating all bubbles (O(N)). Full rebuild only
on initial load or message count decrease.
WiFi TX: Buffer HDLC frame in PSRAM then send with single write()
call. Previously sent per-byte (200+ syscalls per packet), now 1
syscall. Reduces CPU overhead and TCP fragmentation.
Font: Disable unused LV_FONT_UNSCII_8 (compiled but never referenced).
refreshUI() detected and displayed new messages but never called
markRead() or updated the tab badge. Now marks conversation as read
and refreshes the badge whenever new messages are loaded while the
user is actively viewing the conversation.
- Evict highest-hop unsaved nodes first when peer list is full (nearby peers survive)
- Add first-boot SD data cleanup screen before name input
- Conversation summaries cache for faster message list rendering
- Optimize message view refresh with summary-based change detection
- Streamline unread tracking through MessageStore instead of LXMFManager
- Add NTP time sync on WiFi STA connect (fixes --:-- timestamps)
- Throttle LXMF send retries to 2s intervals, increase max to 30 (~60s window)
- Restore message status re-save to disk after send completes (QUEUED→SENT/FAILED)
- Update GitHub org URLs to ratspeak
- Fix LXMF wire format: standardize on opportunistic [src:16][sig:64][content]
- Fix LXMF signature: sign(dest||src||packed) per spec, remove message_hash

- Radio defaults changed to Balanced preset (SF9/BW250k/CR5/TX14)
- Messages screen: sorted by most recent, preview with You:/Them:, green unread dot, timestamps
- Status bar: replace LoRa/BLE/WiFi text with signal bars (green=connected, red=offline)
- Home screen: remove Unread info (shown in Messages tab)
- Contacts screen added (Friends tab)
- Identity manager: multi-slot identity support with per-slot display names
- Message store: fix peer hash truncation, SD directory creation, .bak file leak
- Settings: check for updates, active identity display, info diagnostics
- Migrate all screens to LVGL v8.4 widget system
- Non-blocking radio TX (async endPacket via LoRaInterface)
- Live TCP server switching with transient node cleanup
- Fix UI freeze during radio transmit
- Trackball long-press delete, deferred click with debounce
- Pin microReticulum to 392363c, fix list_directory API
