Option to add augmentation dot once the note is entered
Some people prefer/are used to adding the dot after entering the note, maybe because of the way it looks (note first then dot) or because of language (dotted quarter is reversed in latin language.. "seminima pontuada", the equivalent would be something like "quarter dotted").
I suggest a shortcut function that could default as maybe "Shift + ." to add/remove the dot while in note entry mode. At the moment you would have to get out of note entry mode, place the dot, get back to entering notes..
From my experience, the dot is the only thing right now that can't be adjusted in note entry mode.
