The technology is nothing alike though. Atom is Electron and Javascript where Zed is Rust with its own custom UI toolkit.
And on the current version of Pulsar (the only real community fork of Atom seeing active development), startup time to point of the editor being usable is actually slightly faster than VSCode.
This is the problem, making the fork known to the userbase of the original software. When the Atom text editor was killed by Microsoft we decided to fork it as Pulsar but it was an uphill struggle to really get the word out. We got a massive boost when the youtuber Distrotube featured us in an episode and again with an itsfoss article but we still routinely find people who have been using Atom without knowing we even exist.
Oh god, have we really come around to screenshotting bash.org?
I knew somebody who used the more British version in a game - Hugh Jarse
