The main UI for switching albums, reboot, poweroff, debug info needs to be re-written in Go.

Comments are a bit of a stream of consciouness as @kemonine works through the problem.

Current theory of operation

  • Go tcell/tview/cview main UI
  • UI spawns fim and handles ctrl-c or similar for killing FIM and entering config UI
  • Config ui has options for above and wifi config
  • Monit needs to be updated to monitor for the UI process and NOT fim, ui should handle ensuring fim is active and online
  • FIM should be re-worked to have a smaller fimrc (since it won't have access to the keyboard driect, that's the UI's job)
  • FIM should be re-worked so the UI handles the timeout for the slideshow via config / online changes

Use framebuffer + joystick/buttons

Need to figure out how to leverage framebuffer as a UI ; there appear to be go libs but they are not clear on how to work with the fb for text.
