When Kagi is in verbatim mode (particularly when a search returns no results) add a message like "You are in Verbatim mode. If you want to see more results please disable it.". A few weeks ago I somehow got stuck in verbatim mode and I didn't realize why my Kagi search quality became poor. (I was considering quitting Kagi!).

The exact way I see a user using this feature is that they notice they are in Verbatim mode, and don't think that Kagi search quality has degraded. My feature suggestion adds to the feature of Kagi being a successful company by not accidentally losing Kagi users.
