Ah it does not! Unfortunately I've gotten a bit busy so I've got a few projects floating right now. I did also hit a bit of a snag with the maskByColor functionality (Which would make the automated over multiple frames) which apparently is being fixed in a soon coming version of Aseprite.
However if I find some time I could def put together a version of this that does single frames in the mean time and make note that it will process multiple frames once that api issue is sorted out.
I'm quite excited about this tool as it will be super handy to have but the holidays have been crazy both at home and at the desk job so trying to find time and energy has been difficult.
Hopefully your holidays are going well though and I will try and get something together as soon as I can! 😀 Sorry for the wait!
