When using the hint function (to save wear-and-tear on my eyes), kmahjongg currently just picks a pairing at random each time. It can take many hint requests to see all available pairings (even when there are only a few) as it seems to sometimes show the same one repeatedly. Instead, each hint request should show the next available pairing, in sequence. I've used many mahjongg programs over the years, and they have ALL shown the available pairings in sequence, never randomly (except this one). Some also show matching tiles when any tile is selected or hovered over. Some also allow right-click on a (covered) tile to show covered tiles. These features would be nice to have - especially since so many other mahjongg programs have them.
