(Since RaaA themes can't be posted in the themes section yet, I thought I'd put it here for the time being.)
I made a minimal no-nonsense theme for Rockbox on Android with full touch support. This is only for 480x800 screens.
Short tap on artist/album/track: browser
Long tap on artist/album/track: menu
Short tap on album art: quick screen
Long tap on album art: context menu
Short tap on FFWD/REW: track skip
Long tap on FFWD/REW: FFWD/REW
Short-then-long tap on FFWD/REW: folder skip
Artist/album/track tag info falls back to folder/file display when no tags are present.
The progress bar has a peak meter built in. Looks nice while playing.
This needs a fairly current RaaA build.
