While I understand the logic that led to certain choices for keyboard entry, I do wish there were an option for users to reassign these hot-keys. For example, I do not find the 2, 3, 4, 5, 6, 7, 8, 9 sequence for choosing rhythmic values to be tied closely enough mnemonically with the durations being selected. Obviously, Americans (such as I) and Brits are going to have different preferences – I would be much happier to use W, H, and Q to summon up durations rather than 8, 7, and 6, whereas a Brit might prefer other abbreviations representing Semibreve, Minim, and Crotchet. So an available advanced option of hot-key customization might help.
Beyond that, I find it very clumsy that once a choice is turned on – a note value, the tuplet tool, adding a dot – that you have to turn it off. Wouldn’t it make more sense for it to reset with each new note entered, and then, instead, to have a key stroke that would keep that feature turned on?
I also might argue that the need to press 0, -, or = in advance of hitting A, B, C, D, E, F, or G is counterintuitive, since we do say F-sharp not sharp-F. Again, if more aspects of input could be customizable.
