@lanodan I mean, you CAN make some innovations, GPU acceleration being a relatively recent example and I think also squiggly underlines. Or be a gimmick like Warp or Kitty. :) It's honestly a game of how nice you can make the UI + if it's made in Rust (cuz that's how you attract all soypeople (not just soyboys, we're inclusive here!))
It's not a completely dry place, but I think at this point you're just doing more integration with the shell itself rather than just pure UI/UX things (imo)
