I believe a few buttons in the top ribbon of volumio would be a great addition. These buttons would be user-definable. The user should be able to add a script behind the button.
- Trigger GPIO to switch mains so the speakers have power, or get powered down
- Start Playlist “Kids”. A pre-defined playlist with music for the kids
- Set the mood. Dim the lights and start a love song. (just making an example of the possibilities)
- Start Radio 4 (basicly start playlist)
