Yeah, I've looked at warp.dev. Funny story: I heard about them from Daniel Martí, aka mvdan, the author of the shell library I'm using.
It looks really neat, though I confess I haven't explored it much; dogfooding, don't'cha know. :) I felt a little threatened by them but also weirdly encouraged, since they got $50M in funding. It made me think that hey, somebody thinks a new experimental shell/terminal is a viable commercial product; why not mine? Also, Warp is pretty expensive by comparison (for teams of 6 or more, anyway; granted it's free for 5 or less).
Yeah, getting people to switch will be difficult, especially since most terminals are pretty rock-solid as far as their actual ncurses emulation, and mine still has some rough edges. I'm hoping that I can at least get a few happy users and go from there.
Thanks again for the kind words!
