Github copilot everywhwre. I love the way how it completes the code and even helps write documentation.
But I think it could do equally well for say when you're at the bash terminal, or even writing this comment, the app should just get the context and start auto-completing everywhere I can type, intelligently like copilot. That would be amazing!
