- Context menus (PopupMenu, Nearby/QuickMsg call sites) go back to centring on
screen; the header's discoverable-menu glyph stays, but dropping the popup
out of its corner looked bad on some screens.
- Unread pill badge digit wasn't centred: Adafruit_GFX's classic built-in font
(SH1106/SSD1306) always pads a measured string by one trailing advance
column regardless of the glyph drawn, so centring on the raw width left 1px
more slack on the right than the left. New DisplayDriver::
textWidthTrailingGap() (0 by default) corrects for it on those two backends.
- On-device room Logout: mirrors the app's CMD_LOGOUT (drops keep-alive
tracking, forgets the saved password) so a room can be deliberately signed
out of from the Room options menu, not just re-logged-in.
Not build-verified — no PlatformIO toolchain available this session.
- Add lib/GxEPD2-patch/src/GxEPD2_BW.h: local patched copy of GxEPD2_BW.h
that exposes getBuffer()/getBufferSize() under ENABLE_SCREENSHOT guard.
Include guard (_GxEPD2_BW_H_) prevents double-inclusion of the installed
library version.
- GxEPDDisplay.h: use patched header via relative include when
ENABLE_SCREENSHOT so the patch takes precedence over the installed lib
(PlatformIO adds library paths before -I build_flags).
- DisplayDriver.h: add virtual getBuffer()/getBufferSize()/getDisplayType()
defaults (nullptr/0/0) under ENABLE_SCREENSHOT.
- SH1106Display.h / SSD1306Display.h / GxEPDDisplay.h: add concrete overrides;
getDisplayType() returns 0 (OLED) or 1 (e-ink).
- MyMesh.cpp/h: replace fragile C-cast with virtual dispatch in
handleScreenshotRequest(); extend 5-byte header to 6 bytes by appending
display_type so the host tool can decode the correct pixel layout.
- tools/screenshot.py: parse 6-byte header; add eink_buffer_to_image()
that decodes the row-major MSB-first GxEPD2 buffer with DISPLAY_ROTATION=1
(phys_x = 127-ly, phys_y = lx); dispatch on display_type.
- variants/wio-tracker-l1-eink/platformio.ini: add
[env:WioTrackerL1Eink_companion_dual_dev] with ENABLE_SCREENSHOT.
- variants/wio-tracker-l1/platformio.ini: unchanged (OLED env already exists).
Builds verified: WioTrackerL1Eink_companion_dual_dev SUCCESS,
WioTrackerL1Eink_companion_radio_ble SUCCESS (unaffected).

- Adds the possibility to capture the device screen and save it as a PNG
image
- Wrap the code behind ENABLE_SCREENSHOT build flag, as per instructions
in README
- Added getTextWidth method to DisplayDriver interface
- Implemented getTextWidth in all display classes
- Updated examples to use getTextWidth directly
