CP text as button and "comments" popups fit to their content. If the content is huge they will behave like today, but if the text is smaller than today's popups would be the popups becomes smaller and are placed close to the button(more like a tooltip)
(Hours on the copy project)
Currently, when adding text as buttons and comments that show up in solution mode the popups will have the same size even if the text only contains one word. Often you might want to be able to see the slide when reading the text in the popup.
