While I was working on animation system I gradually realized that COLLADA simply isn't viable for the task. There are lots of issues in plugins for max/maya/blender which make it almost impossible to get a proper DAE file (with skinning and animation etc.) from these tools. So FBX importer was born. I made a new user interface because the old one was a little bit limiting for the FBX and not very intuitive, what i missed the most was a good hierarchy viewer and stats about meshes, animations, an easy way to rename stuff etc.
Here is new importer UI (it is not final, missing a few options and needs little polishing)
And here is video with bug in animation pipeline
