Copy-pasting an URL into Level0 just to edit tags was too much work, so recently I've made it into a browser plugin.

Really simple and obvious stuff: see a tag error? Click "Edit tags" and fix it. No need to go anywhere or deal with the javascript-heavy iD.
Inside it's a bunch of weird hacks. I'm still surprised that in two years nobody has tried to integrate it into the website itself. Like, whom are we making that website for?

@zverik it's unfortunate that there is so little improvement of the interface of the official OSM website. It seems to be stagnant. Is there no one who want to work on it?
