Lock element feature
On various occasions I have been burned when I accidentally selected and moved a note or group of notes or some other type of element without realizing it.
In a previous stage of my life I was proficient at using a CAD program called Microstation. It had a feature that allowed you to lock graphical elements, or a selection set of elements . Once locked, an element could not be modified. The element could be selected and unlocked, however.
I wonder if this could be a valuable feature for a future version of Musescore?
The upside was that you were protected from accidentally / unwittingly changing something that took perhaps months or years to create.
The only gotcha in locking an element that I ran into was forgetting elements were locked and the resulting frustration. There was no visible cue that elements were locked.
