Search box (like in "List Accounts") in the mod_userdir tweak page
Currently, the mod_userdir tweak page is sorted by the account domain, with no options to re-sort by user or search for user or domain. On servers with numerous accounts, this can be a bit of a pain to traverse. A simple search box (or even a live search box) would go a long way in making this go smoother and quicker.
It's obviously not the biggest priority in the scheme of things, but worth mentioning regardless, in my opinion.
