Just FYI, this is now in our development version. If you right-click (or whatever the Mac equiv. is) on the table header, it'll bring up the 'column selection menu' just like before, except now it also has a 'More Options' link that leads to 'Stripe Rows', 'Sort Automatically', and 'Display Tooltips'. You can choose these options independantly for each table. The search results do not have the 'Sort Automatically' option.

By default, tooltips are now OFF for the Downloads, Uploads, and Connections tables. They're still on by default for the Search results and Library.
