One thing I'd like to see as an update or in the next version is a way to create your own music playlist, and to add any songs you wish, in mp3 or wav format. I find it easier to concentrate if I listen to music I'm more familiar with than that which is offered with the program.
If there is already a way to do so, please let me know.
To play mp3 music with mandala painter a very expensive license is needed because of a copyright stuff. Unfortunatelly it doesn't worth... Only .ogg could be possible.
