is there a way to move a file back into an older version?
when I first downloaded synfig like 3ish years ago?, it was functionally very similar to the newer versions I can see now. however, the newer versions have the entire program as one window, which makes it harder to position, run much more slowly, and crash more often.
recently, after not updating synfig since i first downloaded it, I had a small amount of trouble with an issue in an animation, and heard from somewhere that the newer versions had a marginally useful feature (turned out the feature I was thinking of worked differently). so, I opened the animation in a newer version of synfig and started working on it.
the newer version was much slower. I was going to go back to the old version, but i miss-clicked and saved it, and now it seems like i’ll have to use the new version, but it’s slower and such so I’d rather not.
Is there a way to move “newer” files into older versions, assuming they don’t use any features added after said old version? Also, why is synfig so much slower in its newer versions?
