Strongly agree with what
@isladogs has mentioned.
I don't know about anyone else, but I tend to have code/events (related to permissions and the 'updating' of certain controls on certain tabs), and IMO you're much better off creating your own stuff from scratch. You'll be able to 'do' a lot more with it, more easily, it seems to me.
I tend to use an approach that ties together concepts like Tab Control tab names, User list (with permissions of which tabs they can see), as well as updating certain summary stats or notification-type indicators on certain screens only when tab control is changed pages. Has worked out pretty well.
The old, true, Switchboards were absolutely hideous in my opinion. I saw them used a lot in some of my jobs, only by older folks who did not know VBA (or were uncomfortable with it) and needed some kind of out of the box, wizard-driven menu system, so I suppose it had its place but I hated it.
