I'm totally new here so greetings one and all. I have been playing about with Tiled for a game on the old ZX spectrum and I have a small request which I imagine is not that hard to implement. Could it be possible to allow the user to add a 'secondary grid' for groups of tiles? What I mean is, you can see the tile grid, but over that you would also see another, slightly thicker grid showing every 24 x 16 tiles (for example). This would be very useful for creating flip screen style maps that join together.
