Cloud storage with something like git
I am a hobby software developer and deep in love with git. The concept of having a server (maybe self hosted, maybe hosted by a company like GitHub) and the ability to reset my entire project to a former version, or just to see what changed in between two versions is just amazing.
Also there is a personal aspect to that feature request because today I can only use some crappy cloud storage service to store the different versions of my scores, but this is storage expensive.
I would be amazed to have a feature like git, maybe in a more graphical way with nice colours to highlight what has changed from previous uploads.
