Quick Dynamic Toggle for changing Clefs

Musescore introduced the ability to very easily adjust the dynamic markings for a gven instrument in 4.5.0.
A small window appears with the most commonly used dynamics in the middle, with the less commonly used dynamics a single click away through arrows on the left and right.

Let's do the same thing for clefs, and while we're at it, what about key and time signatures?
If a user finds them to be clumsy and not work with their workflow, they can ofcourse choose to disable the feature.
