I'm a huge fan of Text Editors, I've made a few basic ones myself. Thank you for creating Atom! For ages before Atom was a thing I grew fascination with using web servers for front-end UI and thereby using HTML / CSS for a local applications UI, I had seen this in SlickBeard and a few other usenet applications that used a web interface instead of a standard GUI interface to render a UI. I also remember a Google program that did this, though I can't recall the name. It might sound crazy to some to do it this way, but because the web server is localized to your system and your browser is usually responsive once open, every app I used that worked this way was always highly responsive and just worked.

I was dreaming of taking Vibe.d and CodeMirror and making something you could install as a daemon on any machine and code from anywhere. When Atom came out I was obsessed with it for a while, it was a whole other approach from what I was thinking of!

Did you ever do a write up on how you came to the thought of just taking a browser engine and turning it into your own sandbox and what that entailed in the earlier days? That seems like a fun story. Because of Atom we got great innovations that followed, for example Slack, Discord, VS Code, and the list goes on... and on... Heck POSTMAN! Which is probably used or has been used by every developer under the sun.
