Switched to Zed from Webstorm. Only issue is Zed has no vertical tab support. Did create a PR but it got rejected as it does not align with their milestones. Well, using it by monkeypatching the dev build after every upstream sync.
This is the first time I've seen someone talk about vertical tabs in an editor, but I used to make fun of people using vertical tabs in browsers until I tried it and got used to it, so maybe I should try vertical editor tabs...
