But those GM maps are in an extra window taking extra space. So having a GM only layer just for those letters would be useful.
Actually this came up when I troubleshooted a workaround for another user here on the board where he had two huge map image files loaded, just to have one with the letters. Instead the letters could just have been stamped on their own separate layer, but then you cannot switch them on/off without the player catching a glimpse at them. I hoped that there was some keyboard modifier to hold while pressing the visibility button, so I tried all combinations of ctrl/alt/shift, but unfortunately to no avail.
