Premade Regions shows region information next to groups in the premade groups listing and applicant which is particulary useful for players in the Oceanic regions (Australia and New Zealand).
The addon also provides data for the Premade Groups Filter.
When used as a standalone add-on it will show the region of the group leader or applicant. When used in combination with Premade Groups Filter you can also filter the group by the group leaders region.
Please refer to the Addons main development page at Github/Premade-Regions for more information
