Normally selecting tiles from the tileset shows a white rectangle around them, and then a dotted line rectangle for as long the selection remains unchanged. It's understandable that multiple tile selection is not supported in Smart Tile mode, but the complete lack of visual feedback on selection is rather unpleasant and does not convey that anything happened at all. Using the usual rectangle, just always the size of 1 tile, would be preferable.
