Helix is awesome but have been disappointed by the core devs stance toward integrating some form of copilot. It's really difficult to use an editor that doesn't support it at this point.
Reading this thread, I really like the idea of an IPC mechanism like Kakoune uses (and Neovim has IIRC)
If this were the case, integrating copilot or other ao tools would become pretty straightforward!
Can't say I blame them, it's their project after all. Just frustrating because I would totally use helix if not for the lack of that one feature. I actually still use it, but just as a quick way to make edits in the CLI, and not for full time dev. It's a great editor and project nonetheless.
