When trying to use a bang with a capital letter in it, like !LLM or !YT (usually caused by autocorrect), Kagi does not normalize the bang to detect it. For example, !LLM should be treated as !llm and !YT should be treated as !yt. This was how it worked a few weeks ago, but in recent updates, this behaviour changed.
I expected the !YT bang to redirect me to YouTube, just like how !yt does.
