Getting rid of Inactive Accounts in the UI dropdowns

We either need to get a filter, a preference setting or something to get rid of
the inundation of inactive TSA accounts through the client control center. They
are mainly in drop downs. (The drop downs are too big)

These lists are in drop downs of the Search Engine settings, and the Account
Settings.

Let me explain the pain:

To have to assign a campaign to a TSA account, you have to scroll from
(unassigned) to the TSA account. If your TSA account begins with an "end of the
alphabet" letter, scrolling 8 times with the wheel or having to drag the scroll
bar is tedious. This of course is multiplied depending on the campaigns you
have. And the annoyance is grows exponentially depending on the slowness of the
browser interface.

I have found that a lot of the machines here in LA have a 1 second delay time
from when you click on the drop down...from when the drop down actually executes
and appears.
