Adding some Dorico tricks (popover)
After watching Tantacrul's video on Dorico, I've been playing around with the program to figure out what the deal is. Overall I would agree with Martin's opinion about Dorico. It does seem to suffer a bit from people overthinking things and sticking a bit too much to their basic concepts. It seems to me that Musescore's basic system of note entry simply is more flexible and easier to use in general.
However the one trick in Dorico I would love to see implemented is their popover feature, which makes it possible to add key/time/bars/barline changes with keyboard shortcuts rather than having to use a mouse or touchpad. Popover keybindings exist for key signatures (Shift+K), Time signatures (Shift+M) (especially handy for custom time signatures), dynamics (Shift+D), bars/barlines (Shift+B), Playing techniques (Shift+P), Holds and Pauses (Shift+H), Cues (Shift+U) etc.
All these different key-bindings actually seems a bit unnessecarily complex to me. But I think what could work is to have a universal popover (say Shift-T for terminal, or Shift-P for popover) in Musescore which would give you a universal popover where you could type short bits of code (like 4/4 for 4/4 key signature, or F for F major key, || for double barline, etc. etc. etc.). It would be a bit of a poweruser feature but it would give the user the possibility to do more with Musescore without actually having to use a mouse to drag and drop elements from a panel, therefore enabling higher speeds in entering music.
