I was just thinking about building something like this, looks like you beat me to the punch, I will have to try it out. I'm curious if you're able to give commands just as well as some wording you want cleaned up. I could see a model being confused between editting the command input into text to be inserted and responding to the command. Sorry if that's unclear, might be better if I just try it.

I’d just try it and fork handy if it doesn’t work how you want :)
