I am in a position at the moment where I cannot use the new launcher because it doesn’t seem to support the function of duplicating “profiles”. In the old launcher there is a window which allows you to take the existing profiles and make a copy of them, and rename them as you see fit. This feature is essential for creating backups and aligning profiles.
I was unable to find this function in the new launcher as it only supports creating new profiles, there is no option to duplicate an existing profile and/or rename it so that another account can reference/use it.
Further more, it would be nice if the new launcher actually allowed us to duplicate profiles and window settings/chats etc without having to resort to ganking the filesystem.
