Add search-option for members in memberlist

I often have the problem to find am member or my self in servers with a lot of people.

The memberlist is very long when there are 10.000 people on the server and i don´t have a chance to find anybody if the server has different sections for different roles

Maybe it´s easier to find someone in a Online/Offline list but in different rolesections its impossible

A searchbutton for the Memberlist would be very nice or add it in the search bar additionally as "member" such as "mentioned" , "of" , "in"
