Reminds me of MicroViche, the most strangely compelling writing environment I've come across as a text editor uber-nerd. It's an (old?) plugin for Vim that allows one to "pan and zoom through text":
Thanks for that! I found a link there to BigPicture, an "infinite notepad" with zooming. Here's a demo; this definitely looks cool: https://bigpictu.re/demo
Intriguing. Nreal Light AR glasses provide a nicely readable 1080p at 2 meters, ~2 m ~45 deg wide, and 3D (but fixed focus, so long-term comfort suggests keeping that shallow). Which raises the question of what novel UIs for text are enabled by having a head-tracked shallow-3D display with laptop-like fov? Simply panning around a large virtual traditional desktop being meh.

The author also has other videos to demonstrate it (and its evolution, I think) under his Youtube profile.
