Hi, overall i like ur tool, it helped me to save a lot of time. But... i found a issue, if u slice the MZ world tileset A2 in ur tool it is double in high and width but if u export it as A3 then its correct again.
ohh just in case this is also a bug, if i slice my created walking sprite as 1 Actor it gets only cut in half but i i cut it as 8 actors i get each direction seperated.
