I have an idea ..
If it`s possible , will you add a search feature here in future?
That you can search other users , then you don`t have to search them by other users related friends and stuff :)

that is a great idea, have a little icon to search on the top or something!
Searching in the mail section is a bad work-around.
A search field always accessible from the top of the page is much better. From there you can find friends maybe not only by searching usernames, but also based on parameters like country, gender etc.
Other things you could search for includes blogs, groups, images and so on..
I'd love it.

Lastly, I think it should use some google suggest-like technology (just to waste that last bandwith :D)
