I think I'm going to change the code so the groups are created with the name in your locale, but adding in the comment the english translation. Like this the addon will keep working (searching in english) and players will see the NPC's name in their language (just in case someone is looking for groups manually and they don't know the name in english).
Then I will add this two new configurations.
- Check to use your language like default searching language (english otherwise).
- Check to do a secondary search in english (if you checked the option before) or in your language (if you didn't checked the option before).
Anyway, if more people start using this addon, those options won't be needed, because the addon will find every group created with it.
I'll let you know as soon as I have this implemented. Probably next weekend.
