Site Editor - CSS/JS/IMG codepen, ftp (with something like google revision history for the files)
Really just the ability to add sites (name them and add ftp details) local file structure (for development sites) That has the functionality of codepen, ftp, and something like google docs has ....revision history for the files sort of like a basic git repo???
maybe something already exists? it is just an idea
@wayney - Not understanding. Is this a request for the browser, or for the Forum? You put in the Forum category, but then referenced the browser-features topic. Is this something you want to be able to do in, for instance, the Notes panel? Or are you looking for some kind of linkage between the Forum and some sort of repo?
