One heightmap out of many gimp 2.8

[JKLopez]

I’ve kept on playing with it but there’s no realign layer under the layer tab... I put the .py file in the plugin folder and even tried putting it in the python folder because some .py plugins only work in that folder but no dice... I’ve closed and reopened gimp and still no layer>realign layers...any ideas...I’m looking at the top bar menu.. is it in the toolbox or some other place...?
