actually, instead of adding chords like Am add2 in the next updates, would it not be better to have an option that allows the user to define his own chords and even in the voicing he chooses ,and then assigning a shortcut to the new chord? For example, the user defines Am add2 in the following note order, starting from the bottom note, A :

B
C
E
A

then he would just assign a new shortcut.

allowing customization and user definition of chords, would be simpler than trying to add every single chord over the course of years. There will probably be always some chord that are not found in BB.....doing the above would just leave carte blanche to the user, a far simpler solution, I think
