Would be nice to add a simple window with all the nicknames you were able to collect during gameplay. For example, a title system. You gain a nickname, and you save it somewhere with a script call. You go to this window and it shows all the titles you got this way, allowing you to switch from title to title. Something like a title collector.
That’s a good idea. One day I will probably get around to trying this :)
wow, awesome script galv!!
but, it would be best if you update it like what pinka said :)
