This is great, but it's a little clunky for cubes. It would be nice if the layer group was split into 2: 1 for the back 2 tiles and one for the front 2 tiles... that way the preview is accurate to the environment it would be placed in
It seems like it should be theoretically possible with what's already there by duplicating groups but I couldn't get the plugin to update the offsets of the modified groups even if they showed up in the dropdown...
