Clicking on this will reveal the "Settings" for that particular list. These control which columns appear for you in which order (and NOT the filters; more on those later).
You can set the default number of rows per page from 1 to 999; you can drag column headers in the list to order them; and you can drag column headers back and forth between those in your list and those hidden from it. Click Save Changes to apply, and Restore Defaults to, um, yeah.
The gear icon is sported by the following list views:
- My List (where you can "run" saved lists and searches to see the contacts they return)
- My Folders (a list of folders in which saved lists and searches are stored)
- Individual folders (a list of saved lists and searches in that folder)
- Quick Look Up (a way to find contacts by searching on their personal information)
- Event List
- Bulk Upload Batches (the administration zone for bulk uploads and applications)
And the list goes on. Just look in the top right corner and you might see a gear there.
