Tile groups

Hi!

Ive been using this program for about two months and I think a good idea could be making tile groups, just like the layers. Im working on a game and I have tons of texture tiles, and several variations of each tile, to the point that I have to create a new document and import the tiles in the same order just to know what I'm selecting. It would be so much easier if I could group and name those tiles (80 or so).

I don't know what you think
