I think most Fusion users hate the way the software forces us to save a new version even if all we are doing is save are one or two minor changes that are definitely not worthy of a whole version.
Anyone who's used Git knows how version control is supposed to work. Meanwhile, Fusion floods your version history with mostly pointless versions that look practically identical. Nobody is going to bother to type in a version description every single time when all that was done was correct a typo. That version description box is really a flow killer—I just wanna hit Ctrl+S every now and then and continue working, knowing that my work is safe.
In theory that's what autosave does, but all I can say is that I've lost count of how many times autosave has failed to save my work. IT DOES NOT WORK PROPERLY. Somehow it seems to work always except when you actually need it. Furthermore, autosave saves at regular intervals, whereas I can save after making changes right now without having to wait for autosave to hopefully do it's job 3 minutes later during which time the program may have already crashed.
