This is a very little thing, but I've noticed that when I import an OBJ file (or any other model file), Animator writes a Fact file to the same folder (makes sense). But if I import that original OBJ file from that folder into a new project at some other time, Animator will overwrite that Fact file - if I've changed my import setting this throws off the original project. I know I can export the model or move it to prevent this, but if it just wrote a differently named Fact to that folder that would help (leaving both intact). As I said - a very small issue, but potentially frustrating.
