I noticed some features can be accessed in multiple locations. For example, walls and floors can be created in Architectural and structural (in structural, walls and floors can't be created by face, though). Columns in architecture can be architectural, and structural. In structural, you only can create structural columns. The steel tab also has "connections", and so does the "structural" tab. I'm sure there are more examples.
One might even get rid of the "create structural wall" button and just make the "structural" a checkmark when creating.
Also may be good to allow columns to be switched between architectural and structural (like walls can be changed). I know, this may be harder to do since those are loadable families. but doing it like for the walls that a checkmark can enable the structural functions would be good.
UI would be easier to navigate if each item only exists once and a new user only has to learn one way to create an item. Some of that may be legacy when Revit had distinctive MEP/A/S versions.
