and, the npc editor is just showing a grey box at the right: it would help if we could see the actual animation, that way we could go back and forth between the pbm editor and the npc mode to see if we like how a monster looks
... umm ... but on second thought we probably don't need that :X
edit
h, pbm editor: undo key (ctrl+z) implementation (lets say, up to last 500 pixels? can't take that much mem <_<) and / or "save a backup" needs to copy the current .pbm and put it in the "backups directory"... use there is that if you edit an image for a while and want to compare with a while before you've got your old image in the backups...
but this really does do everything, it'll just take a while to get used to.
edit^2: save and test crashes on me, even after I de-read-onlied all the fiels...
