Add config.LoadFrom/SaveTo for arbitrary paths and thread a --config
flag through both entry points:
- CLI: --config loads a file first; explicit flags override file values
- GUI: --config selects the settings file used for load and save
- tests for LoadFrom/SaveTo and default fallback
- tray icon and tooltip now reflect engine state: grey when stopped,
green + live frame/drop counters in the tooltip while streaming
- generate a proper app icon (assets/, via cmd/teleportfling-icon) and
embed it so the window and tray carry the icon without runtime files
- add a .desktop entry template for launching from an app menu
- run Fyne UI updates (status label, tray icon/tooltip) on the main
thread via fyne.Do to satisfy the threading model
- config: validate port/quality/fps/source/stream-index ranges on load
and before engine start (flinger.Config.Validate)
- discovery: add Announce option to disable multicast (GUI checkbox,
CLI --no-announce); absent JSON key keeps the default true
- backpressure: count dropped frames in the TCP sender, expose via
engine Status and a live counter in the GUI status label
- docs: record M3/M4 decisions and X11 coverage via the portal backend
- internal/gui: settings form (name, port, source, quality, fps, audio)
wired to the flinger engine, config save/load, start/stop toggle
- system tray via Fyne's StatusNotifierItem: Show (raises window),
Start/Stop, Quit; left-click shows the settings window
- cmd/teleportfling-gui entry point
Verified on Hyprland: tray icon registers, start/stop streaming works,
window shows and focuses from the tray.
