Sometimes you need to add a player to several groups. For example: One constant, the second has a lifetime. The second must overlap the rights of the first at the time of its existence, this requires priority.
We use the rscPermissions plugin.
Here it is realized, that's the field
inheritance_priority.
The absence of such a mechanism stops us from switching to your plugin.
Thank you in advance! We will wait for the update.

This exists already.
