Recreate functionality of player menu as custom menu
I have a project consisting of approx 80 slides across 4 scenes and I'd like to build a custom menu that mimics what the player menu does. The course will be restricted (can't jump ahead but you can revisit). The features of the player menu I'd like to have are the 'greying' out of visited slides and of course being able to jump to a slide. A scrolling panel is fine (though a collapsible one would be awesome). The idea is to have it in the slide master.
So the question is, does anyone have any tricks besides setting up triggers for every slide title in the menu, based on t/f variables from each slide?
Thanks for any suggestions!
