I think Tabby is a similar project, but personally I spin up and throw out terminals very liberally. Tabby had a horrendous launch time, something more than a second which constantly bothered me while trying to work. I'd love to see how quick this is though!
They do have Linux and Windows versions coming and claim they're going to gradually open source it so there's that, but yeah, doesn't exactly inspire that much confidence lol
Warp has discoverability features that would actually convince me of using a "modern" terminal - like instant tooltips with documentation.
That said, call it trust issues, but I'll never use a closed source terminal.
I'd like to see more user-friendly features like this that are terminal-agnostic. Manually checking manpages is so slow and fickle. Having the equivalent of an intellisense for the command line would be awesome.
Yup, I feel you. It's something I've always wanted myself, and I find myself hoping the OSS alternatives eventually implement something similar. For now I just make do with things like tealdeer and whatnot.
Edit: Just stumbled upon navi, the interactivity looks a lot closer to what we want than tldr and friends at least
