I work on this from time to time, adding features as they become necessary.

Items from TODO list that are done:

• Finish and refactor path_picker
• Fix Adafruit shield display backlight management
• enable instead of select when adding a wireless network
• "format_for_screen" function for text
• Changing UI elements to use threading.Event
• Move app manager to separate class
• Menu contents refresh hook

Not much, but I'm not spending too much time either. Unplanned but added/fixed things:

• Added arbitrary script and command launching to Scripts app
• Added a Pomodoro tracker app (works with PomodoroD daemon)
• Added backspace function to CharArrowKeyInput

Next up - writing better documentation. I've started to get questions about writing new apps, so the docs have to be there, and they lack some important details. Some UI elements haven't yet been described, and there should be more examples for the existing ones. last but not least, I should finally fix PiFaceCAD or at least say that it doesn't work because it definitely doesn't now.
