I'm trying this out and first notice that unlike the old editor, I don't have access to previously-named references (the "Named references" button in the old editor). That was an extremely useful feature. Are there plans to reinclude it?
Also I'm wondering if anyone has been developing some sort of tool to save edits before clicking "Publish", sort-of what the extension Lazarus does (which doesn't work on my browser). This would be all sorts of useful and reduce stress so so much.
