Yeah, I completely see what you mean. That's pretty much what I meant by "abstract ambition" in my original post. I feel like I've spent a fair bit of time building modules that are generic enough to be the basis for a few different apps, but the whole doesn't yet do anything specific well enough.

That's why I felt like I need to release this sooner rather than later. It would be appealing to go on polishing the app for an imaginary customer who happens to be just like me (my other application, Conduit Live, went down that drain)... But it's healthier to face criticism and try to figure out if there's some potential customer group(s) out there that I didn't anticipate.

FWIW, I feel like there might be something interesting to be done in the intersection between realtime graphics and video on the web. Flash has a lot of cool technology, but nowadays you need to be a coder to take advantage of the new stuff like Pixel Bender shaders or the Alchemy compiler -- Adobe seems to have "outgrown" the designer audience who originally made Flash a success, and I think that's a mistake.

Re: your points about Radi -- there's a big hole in the <canvas> publishing functionality currently, it doesn't export all keyframes. Sorry about that, I'm hoping to fix that ASAP. The keyframing UI is not very well thought out, and needs a lot more work. To make polygon shapes, choose "Draw Shape" from the toolbar and click away in the viewer. There's no exposed way to limit the shapes' visibility in the timeline either (internally there's a concept of empty keyframes same as in Flash, but it's not in the UI).
