A way to pick a tile by clicking on the map
While editing maps, it would be nice to be able to pick tiles by clicking on those that already exist in the map itself. So you could reuse the existing tiles more easily.
The middle-mouse-button would be great for this, as far as I'm concerned. Or Alt-LMB or something.
Unless there's already a way, and I just couldn't find it.
On a side note, the middle-mouse-button would also be my preferred way of panning the editing views, both for maps and sprites.
