Character Names and Dark World Theme?

[Royaken]

So I have 2 questions here and I feel like the 1st one is not gonna be doable xD

1st, can I increase the amount of characters a character can have in their name? Maybe as a default I can but not when changing the name, correct?

2nd, I thought I saw this some where, but can't seem to find it now xD. I might be blind. I want to keep the Dark World theme when not on the Airship and only have Searching for Friends when I get on the Airship. How would I go about that???
