Interesting. I've wondered how to build a media or presentation editor like this myself.
Looks like it centers around the canvas object and a bunch of divs pretending to be widgets. I found this interesting as well, from the readme:
It is written in 100% plain JavaScript and has no dependencies.
It's 100% free, no ads, no tracking, no accounts, no nothing.
All processing is done in your browser, no data is sent to any server.
So no big framework, eh? I'm kinda glad to hear that, yet wonder how maintainable it will be in the future. Are there any books/blog-series that go over how to build one of these things?Also looks like this was cranked out in ~6 months or so (with a big gap in the middle), impressive.
