The text search part of the Kagi main page could also accept drag-dropped images. To image search, you have to click the "images" button first, then the little image icon, then you can drag and drop.
For convenience, a drag drop could just work directly from the main page. Right now it just opens the image in a new tab. (default behaviour for my browser)
This would be just like regular reverse image search, just with 100% less clicks (unless you count the drag-drop action, then it's 67% less)
