In the Raspberry Pi menu (the "Start"-like interface you get by pressing Super aka Windows key) there are programs organized in folders (or submenus) depending on their category.
The Pi is going to be used at school and Musescore will be used to teach, not to play music, so I don't think A/V is the right category for that program.
Instead, I'd like to move it to the Education tab that appeared after installing GeoGebra.
I'm running Raspbian Jessie with Pixel Desktop on Raspberry Pi 3. I have Internet connection and a lot of free space, so I can install programs if needed.
Is there any way to do this?
