Imagine being able to "ai {some query}" inside krunner, and it opens the mini window mode. Anyways, I've been looking for an AI plugin for krunner for quite a while but haven't found one, and its on my backlog to make it happen.
If you're fine with such a feature, I don't mind developing and making a PR when I've time someday after clearing my own backlog of tasks.
