This would probably require restructuring of some systems like the ground tiling but it would be really nice if I could have the walls snap to the vertices of the grid rather than the center spaces of the grid. When playing ttrpgs generally the walls are not drawn in the center of the grid space because it introduces ambiguity as to where the players can stand and it takes up a lot of room.
Also minor gripe but the default skin seems to be absent from the palette editor, had to restart the program after messing with the palette a little to reset to the original skin. I might just be missing it though.
