Hey.
I have a ranking system, and I've made a custom plugin to show the prefixes and suffixes in the tab and chat. So I've added permission of:
chatandtab.none and chatandtab.vip and etc. I want VIP to inherit every single permission that none has, but not inherit the chatandtab.none.

Is this possible?

If another group has the required permissions, do
/lp group <group that should get the perms> parent add <group that has the perms>
and then deny the permission you don't want for the group with
/lp group <group> permission set <permission> false

/lp group vip permission set chatandtab.* true
/lp group vip permission set chatandtab.none false

Although, I'd suggest that you change your custom tab plugin to simply infer .none if they don't have any of the other permissions set
