Just want to let you know that I'm a huge fan of Zed. Thanks for creating it. Been using it for three weeks now.
I love that you've put so much effort into Zed being a keyboard-first editor. Mouse is useless in Zed, which is how it should be.
All the other editors (Atom, Sublime etc) force you to use the mouse, or their shortcuts are so difficult that it's not worth the trouble.
Tabs are indeed useless and it's perfect that you avoid them completely.
I think you should continue developing it, it for sure fills a void.
