It looks alright, except for how we pass the state into the command parameters. I have some ideas that we can discuss on discord

I marked this as a draft because I haven't tested it personally (compiles + local tests pass) and it still needs a bit more work. I'll get around to it sometime tomorrow unless someone gets to it first

1. Docs about the FromCommand trait
2. remove with_window attribute from everywhere since it's completely unread
3. test it actually works with real applications lol
4. changefile
5. am i missing anything?
