I really cant follow this logic, you know your way around cinema yet you are doing this because of the new users? I really wish you the best, as far as I know all DCC have changed interface, even UE4 to UE5.
With all due respect, I also am a customer, I had Cinema since R9, I used it along XSI since R12, and switched around R14/15 because of my work. I never ever, had a problem following tutorials from old interfaces, not even when I was looking at Blender 2.8 and learned from 2.79 messy UI. The only time I had issues was when I was learning Houdini and they changed Vex or Point node (Houdini has some major issues, you often see tutorials updated because of deprecated nodes)
I started in this field of work with 3dstudio 4.0, Parallax Animator* and Softimage 3D, Maybe cinema users are different but I´m really glad we are not using the same interfaces from 30 years ago, just because newcomers will have trouble adapting.
*edit.. I think it was Called Parallax Matador? Im too old to remember, it was on Silicon Graphics... oh boy.. I had to learn Windows from Irix too?
