Every application is a work in progress. They either improve continuously or in point releases, step by step.

We were using musescore for our sheet music while I was playing in a symphony orchestra and, it was very capable back then. It was missing some very niche things (like Turkish Music Coma notation which divides a note to 9!) but, it was vastly usable.

I'm glad they didn't stop and moving forward. It's a very nice piece of software.
