I have a suggestion you might want to take into consideration.

I, being fairly acquainted with Musescore, am able to find my way around better than some, but to people who are new to Musescore this feature might help if it were added:

In PowerPoint 2016, there is a box that says "Tell Me What You Want To Do." If you type "new" into that box, for example, it will give you some suggestions such as "New Slide," etc. I was thinking that if Musescore had that, then people who are not familiar with it could use that. Thanks for you time, and I hope this helped you (or at least people using Musescore.)
