I suggest that there should be a way to remove friends lists: I have about 20 already. eg. /friends delete <list_name> This would be of great use, I don't think it would really take much time. What else is there to say?
For once I will agree with you. I've got at least 20-30 friendslist from all the back to 1.2.5. I definitely would like a way to delete them.
We are already exploring the addition of such a feature, but at this time we do not have a timeline as to if or when it is to be expected.
While this is not added, feel free to PM me asking for it. Don't forget to include the complete and exact name of the friends list you want to leave or delete.
