- Basic copy to/from device support.
- When refreshing library/albums, only affect parts of the model that have
changed. (Previously the whole model was replaced).
- Allow songs to be deleted.
TODO:
- Make song deletion actually work
- Copy/delete album covers
- When deleting a whole album/artist, need to delete corresponding dir if it is empty.
- MTP devices
when in a lower level, and search to an item that matches higher - the model navigates up - but the nav buttons dont change!!!!
this leads to a crash when press nav button!
e.g. Im/
Final Front../
El Dorado...
A/
B
If we are in 'B' and type 'Dorado' then we change to 'Im' - but nav buttons do not!
