[Suggestion] Search System for Friend List, Guild, Ignore List, Stable

Wouldn't it be great if there's a Search System on Friends List, Guild, Stable, Ignore List,, Like the one in Auction?
It would make things easier. Such as:
-Finding Member that you want to kick, Unfortunately the member's name starts with Z and your guild member is 1,000+ .
-Finding a pet that's lv 1. Unfortunately your pet is 50+

What do you think? (P.S: My English is not that good, sorry)

Many people have thought of something similar like that. Would be a good thing to have a "search bar" for finding something quickly when needed etc
