The default 1Mb/Min AAC Setting with 128kpbs is decent but by no means really good and the 10.1MB/Min WAV is a bit much. A 192 or 256kbps AAC bitrate would be close to transparent and would probably pretty easy to add. Maybe add both options if nothing speaks against it.
Another thing that would be awesome is a function to auto record sessions from the moment you first hit play. Sometimes it can be forgotten or a practising session develops into a really nice mix.
Bonus Point: Add fixing for recordings that are broken due to not properly stopped recordong like from a crash.
