I really like that the label for an Action can now be computed with a formula. How about we extend this to hotspot buttons, controlled access section title text, table tabs, etc.
Similar as Hide when formula is true. Designer can set section as always open/close, but in the case when formula is true (ie. status field) sections is open by default.
I would like to see possible to use your own images for collapsible sections. For example a plus / minus image instead of the 'Notes' twisties.
