I really like this app, I wish I could apply filters such as only showing Bass songs, or that it'd show what tuning these songs are in. A longer list of songs would be great too, instead of getting 130+ pages of 10 songs each
The Custom Tunings don't seem to work for me. I replace the cache.psarc the easy way but I still have entire lists of just "Custom Tuning". The list of possible tunings works, showing all the available tunings, but not the Learn a Song list.
