http://lighttable.com/ might be interesting for you if you've not seen it before... It's looking at some of those concepts. (I've not used it personally, but heard good things)
Definitely avoid lighttable. Unfortunately it is in a zombie like state with tons of open bugs, outdated dependencies and creators who abandoned the project. If you want a simple experience in an "electron" editor, I highly recommend VSCode + the Calva plugin.
