This is fantastic! Congratulations on all your hard work -- and just in time for NaNoReNo! Can't wait to try all these things out...
EDIT:
Downloaded 1.8.32, thought I'd give the 'hotspot' action a try. I couldn't select a scene for the clicked hotspot to jump to: a list of options flashed up, and disappeared before I could select anything! (It was like this for both the 'On click' option lists).
ANOTHER EDIT:
Exported the file I've been working on -- when I re-started Capsule, and tried to import it, I got an error message - 'Invalid file format'. That's a bit worrying...
