I have built it because I'm a musician. That being said I am interested in serving my customers / community and am open to what features would be needed / what user experience would be desired.
Some video recordings would be extra nice also, that shows the software in use on an example audio project. Including showcasing of how you work with the revision history and branches, and how it enables collaboration.
It's free for local use (meaning no cloud sync, or collaboration features: merge requests)
