Could we have more linkshell, friendlist, and blacklist slots?

Just saying because I've met and helped out lots of PUG folks who turn into friends, but can't add anymore. Now since we have cross-world connections, I feel that we should have some more linkshell space and friend slots to accommodate that.

Could we also have an easy way to switch linkshell positions? I.E. /L1 --> /L3

Even with clearing out (deleted)s I still run out of slots to add friends. I'm sure everyone would want unlimited /blist spaces. Having more linkshell slots would help out a lot too.
I think it would be beneficial to what FFXIV has always done, connect with friends and pew pew things.
