how to best *not* to compute the UI

I’ve noticed there’s a difference in speed wether or not I have a number of panels open, even though they’re hidden by other panels (kind of like a tab menu).

Is there a way to minimize drawing/computation time? Maybe using enable and display? (the top tab contents are not displayed, but I think children of the ones that are hidden may be having their display flag on - at least the selected ones, the ones you’d see immediately if you turned on the parent tab).
