Hey, guys. I posted in the general forum https://www.fantasygrounds.com/forum...m-tiles-I-made
Since there's no way currently to type text on a map layer. I took a few hours and made some tiles (A1, A2, B1, B2, etc) for letters A thru L. Just go to map layers, put them as a tile to be set down, and set the layer to Visible to GM Only.
