Hi.
In looking through all the examples and themes here, it's obvious that there's a technical issue with graphical overlays, else at least one theme would implement them.
If they're currently unavailable (easily, anyway) can you fake them by flipping background images on an event? I know there are animated WPS screens. This would at least be good for echoing a softbutton presses on a touchscreen interface.
Sorry if this is basic stuff, I did search both the wiki and forum, and words like overlay, animation, animated, etc. turn up little or nothing.
Thanks in advance!
