This would be great. If it’s got nothing to do with Max at all, which I don’t think it does because it’s the same across Sketchup, Rhino, C4D, Maya, etc., then maybe some kind of .ini file, where you can create and map certain controls to the host application, so for example, I could make a pulldown with the same render options as Max’s blowup, region, selected, etc. and just map each item to the maxscript command for that.
We’ve been exposing more and more of the VFB as the builds go on, so hopefully we’ll get to the point you want 
Best regards,
