I like very much that “search by name / email” has been added to some Admin pages.
I could really benefit if some of the other Admin pages were sortable. So much so that I am looking into writing a userscript. It could be relatively easy for the Admin->Users->List (table) pages though not so easy for Admin->Logs (divs) by using jquery.sortable
Before I get too far into it however, I thought I would float the idea here in the chance that it could be considered as something to add to the Core.
