Is there an "eyedropper" tool that I can use in the editor where I select the tile in the map and it can highlight the tile in the tileset?
Yes, right-clicking while having the Stamp Brush will capture the tile (or a dragged rectangular area of tiles) from the map, so you can paint with it as well as see it selected in the Tilesets view. Since Tiled 1.4, this will also change the currently selected tileset when all tiles are from another tileset.
Oh that's awesome! I'll have to give that a try. I had a really large tileset with very similar looking tiles and was struggling to quickly identify the tile in the tileset from a tile on the map.
Hey, sorry, you won't let me download because it will be that you won't let me, I'm sorry if it's misspelled, it's that I'm using google translator
