A thank you like this goes a long way, no donation link necessary. You could hunt down the flattr link on the jolla store page for my sleep timer 'slumber', but that's way too much work.

People on Openrepos showed interest in more file formats, so
Release 2 is out:

• now lets you open *.mp3, *.m4a, *.m4b, *.flac, *.ogg, *.wav files (ability to play should equal system media player)

Let me know if there should be more file extensions allowed (and which ones).
