Some small ideas for improving current note input workflow
In a few previous discussions such as https://musescore.org/en/noteinput_redesign#comment-947093 and https://musescore.org/en/node/303858#comment-1006519, the idea of a note input workflow has been mentioned is rather unlike anything MuseScore current supports directly, but it occurs to me there might be a way to make something like this happen pretty easily.
The idea as I understand it is is that people want to enter notes not using the mouse to click pitches and not using note letter name shortcuts, but using some sort of scheme where you enter a note at the same pitch as the previous note then use the cursor up/down to adjust it. The idea would be you could enter a scale as shortcut, up, shortcut, up, shortcut, up, etc - for some particular shortcut. The trick is in figuring out how to specify the duration.
BTW, I gather this is the native method for entering notes in Capella, except I think it's the other way around - up/down affect the note input cursor more or less like it does for tablature input in MuseScore, then you hit the shortcut to enter the note at that pitch. Sibelius has a kind of hacky approximation of this using the "R" command to add the note, then you change its duration, then you move it up or down.
In MuseScore, "R" does exactly this in step-time note input mode, but without an easy way to specify a different duration. Q & W exist but aren't necessarily the most natural to most people, and it can require multiple presses. Somehow I think people would prefer to just select the duration. I have considered and actually implemented a command that would apply duration (and accidental) retroactively in step-time note input mode. So you could press "R 4 shortcut" and it would repeat the previous note then change it to an eighth. This seems like it would be quite useful for this workflow..
But another idea is to use rhythm mode, which already provides a way of entering different rhythms wich a single keypress - just type the number for a duration and a note is entered immediately. The only problem is the note is always the middle staff line. That's because we initially envisioned this as a mode to enter a bunch of "dummy" pitches that you later go back and use repitch for. But, it could totally be used for the workflow I am describing if only pressing a shortcut used the last pitch rather than always jumping to the middle staff line. For people using this mode as originally intended, it wouldn't change anything. but if after entering a note you immediately repitch it using the up/down keys, this would allow repeating the previous pitch but with a new duration by simply pressing the duration. Seems a nice win for lots of purposes, also including things like drumset input, you might well want lots of notes of the same pitch over and over but not necessarily the middle line and definitely not all the same duration.
Biggest drawback of using rhythm mode in this way is ties, which are awkward to enter currently. Still thinking about that one.
