Using the build of the C1 Ribbon (2.0.20082.98) there is still no editor for super tooltips on the groups or buttom components of the ribbon, although as you correctly point out you can paste html code into the tooltip property and you will end up with a super tooltip in the running application. However as my html is not exactly brilliant it means going to the main ribbon form itself, using it's super tootip editor (which is in place) creating my tooltip , copying the html, canceling my changes, returning to the item I actually want the tooltip for and pasting the result into the property.
Firstly are we going to see a tooltip on C1Super Tooltip property for ALL ribon items anytime soon(with a proper editor), and untill such time as we do is there a more efficient way to create then for ribbon items other than the approach I have outlined above?
