As a proof-of-concept experiment, I tried to do TiddlyWiki-like saving for Amber. So if you do some changes in the code, it can then save the whole "image" as a single HTML file without other dependencies. Only the Legacy IDE works: https://pavel-krivanek.github.io/amber/amber.html
Unfortunately it's a kind of show stopper for those who don't know npm or nodejs and don't really want to deal with it.
