What's crazy is that the landing page doesn't even mention Mac at all.

I'm getting very annoyed by things that don't mention they only work on Mac until you go to install them.

LSP support is semi-built-in, but lots of improvements to come in that area apparently to support more language servers. With Python, it currently only has Pyright built-in which is more of an annoyance if you're working with code where the venv is inside a container but there's very active tickets on their GitHub about building out the LSP support. I currently use it as my second editor - I have Sublime set up to be pretty much perfect for my usage, but Zed is catching up fast. I find I'm very fussy about editors, I can't get on with VSCode at all, but I feel warm and fuzzy toward Zed - the UX is great, performance superb, external LSP support is probably the one feature stopping me using it as my primary editor.
