Bravely default norende village editor help

im playing through the game again and this time i actually want to level up the village to max (dont really care about nemesis) how do i add more villagers?

also i know about the villager save editor thats on github i have 0 idea how to even open it

Did you find anything out?

heres the village editor, just open the colony0.sav with the editor and changue the villager value and then hit save, profit.

Im using windows 10 and it doesnt have the save option, only the parameters to changes the values. Im doing something wrong?
