Let user pick and choose columns that are displayed in the grid
Give users the functionality to select columns shown in the grid and to order them as they like. Tie in functionality to let them 'save' the columns they've selected so that the next time they hit the grid, it remembers their selection.
See column chooser feature in version 6.

"The column chooser does not persist. The columns displayed resets whenever grid or the page refreshes."
It doesn't look like the chosen columns persist. That feature would be great. Can you add it?
