Hi,
I've been messing around with this plugin for quite some time now. But I am not sure if it is a bug or issue at the moment.
When I would make .json file for the groups it seems when I put in true for the hideifnotprimary is seems to ignore it.

Hope to hear from you soon ,
Megabyte

Whoops my bad
I actually manage to fix it wasn't a bug or issue just the priorities where backwards
