it works better with beta9, still there are some little concerns:
I get this windows when opening the project
and after (big window cut, no file displayed):
filter is too strict and doesn't include executable extension, but the name is ok, using no filter ("all files"), display the program and I can use it.
FBX file is imported more or less well, it is just a simple mesh with UV but nothing fancy (skinned mesh, anim, etc).
I guess filter need to be a little adjusted for all OSes Godot is available on.
