twmap-edit. among others less relevant options, there are:
--remove-everything-unused: removes unused images, sounds, layers, groups, envelopes--shrink-tiles-layers: scales down all tiles layers to remove any obselete air/other tiles from the border$edit --remove-everything-unused --shrink-tiles-layers with any amount of options. (if you would use the command line tool, you would do nearly the same,twmap-edit --remove-everything-unused --rotate path-to-input-map path-to-output-map)
$optimize is only a shortcut to do $edit --remove-everything-unused --shrink-tiles-layers$edit --help in any testing channel (the output is a bit big so maybe do that in #🎉caterpillar3)--shrink-tiles-layers is: in all 4 directions, detect how many rows are duplicates at the border. then, remove those duplicates, but leave at least a 2x2 tilemap, shrinking the right and bottom border is prioritized (edited)
