I am using musesore with my guitarstudents. I am doing the same with Reaper (DAW). Both sotwares can be personalized. But to give this persoalization to my students is with reaper more comfortable.
Reaper is able to export the all personal settings and import the settigs into a installation at a different PC.
Also is Reaper able to make from the PC version a USB-Stick version.
I know the portable version, but it is rather slow, to work from a USB-Stick.
