Quassel IRC

I find myself often in the following scenario.

I have a question to person X in channel Y because I've found an odd piece of code via git-blame in some project.
The problem: I don't know the nick name of that person. But most persons have the correct real name set and I find myself going through the nick list and check if I can find him via the real names provided in the nick tool tips.

So, in order to make this a 'bit' more efficient for me and others, probably, too:

Quassel obviously has all the real names of the nick it knows in memory. (It periodically /WHO's the channels, I guess)
I propose adding a custom dialog with a search field, a list view and a search button (in its simplest form).
Pressing search then basically goes through the cache from /WHO and lists the entries that match my query.

Example dialog: | Search for real name: "Kevin" | Results: | - Found "kfunk" (Kevin Funk) on channels "#kde, ..." | - Found "ervin" (Kevin Ottens) on channels "#kde, ..." | (...)

Note: This, of course, is not only limited to the <real name> field. Other query parameters could be set within that dialog as well.
