Our ribbon button actions are awkward! We need the ability to interact with them more dynamically at runtime. Ideas: Change Office.Ribbon.RequestUpdate() so that it can change a ribbon button's lab...
I agree. This option will be very useful.
Current MS strategy seems to go the way, that a ribbon-button should open a side-pane. And all the main logic should reside in this side pane. We are following this way, but it would be more elegant if one could update or at least show/hide ribbon buttons conditionally.
