Problem:
Currently, overlays in Captivate can only be triggered via bookmarks, and each slide overlay can only be used once. Local, reusable overlays directly on the slide do not exist. This limits flexible interactions and reusable designs.

Suggestion:
- Trigger overlays via clicks on buttons, images, or text links, without using bookmarks.
- Allow multiple uses of overlay slides, so standard popups can be used multiple times.
- Custom/Local Overlays created and displayed directly on slides (similar to the "Click to Reveal" widget, but freely definable and reusable). Various types could be possible:
- Dialog or info windows as overlays
- Popovers / small info boxes that appear on click or mouseover
