Popovers and slide controls are new design tools which are elegant and useful alternatives to standard buttons and tab controls.
In relation to popovers I have been trying to find a way to (1) convert an existing button into a popover, (2) select a text object/image/field and turn it into a popover, as we have always been able to do to create standard buttons. So far I have found no way to create a popover except from scratch using the layout tool provided. Granted you can then configure it to include an image or text in such a way that only the latter is visible, but it seems you have to follow that process.
In relation to slide control objects, it would be nice if it wer possible to convert an existing tab control object into a slide control, but again my experience so far is that you must start from scratch using the layout tool.
Has anyone found a way to overcome either of the above? And if there is no way, would this be a useful thing to add to the wishlist for version 14?
