Eliminate most "Properties" dialogs in favor of Inspector for MuseScore 3
In MuseScore 1, the only way to access options regarding any given object was to right-click on it to open its Properties. MuseScore 2 introduced the Inspector, which did away with many of the inefficient Properties dialogs in favor of an always-present sidebar, and—crucially—allowed changes to be applied to multiple selected elements at once.
There are many examples of Properties dialogs that have been eliminated due to the Inspector. "Note Properties" is a particularly obvious example. If you still have a copy of MuseScore 1 around, check out "Tempo Properties" and "VBox Properties" and "Tuplet Properties." ("Slur Properties" will give you a laugh.)
But there are still several of them hanging around in MuseScore 2, when it's pretty clear they shouldn't be.
"Articulation Properties," "Fretboard Diagram Properties," "Line Properties," "Text Properties," "Staff Text Properties" and "System Text Properties" are definitely ready to move into the Inspector (with perhaps some modifications). This would pretty much take care of #24436: Changes made in Text Properties do not affect all selected elements, #20699: Move "Fretboard Diagram Properties" into Inspector, and #117831: Double-click on text of text line to edit text.
"Staff Properties," "Measure Properties," and "Time Signature Properties" might be better off as the separate dialogs they currently are. But instead of being only accessible from a right-click, let's add a button to the Inspector allowing these dialogs to be opened, depending on what is selected—as Marc Sabatella suggested .
To sum up, we've got a great thing here with the Inspector. Let's make fully utilizing it a priority for MuseScore 3.
