[palosanto]

palosanto - I just tested the return to library action after assigning it to the top right corner and it worked just fine. I do not support touch actions when annotating though, so you'd need to exit the annotations mode first.

Mmm, 
I had always assigned the top left and middle areas to 'Annotate song' and the top right to 'Return to library'.

I used to be able to return to library in both situations (annot and display) with both the finger or the stylus.  No I can only return to library while in display mode and only with the finger.  If I tap with the stylus, the annotation menus show up.
