It would be really useful to have an option to make the table header in Overview always visible, regardless of where you scroll-down in the page. We have a huge list of both servers and triggers and Overview get's really hard to follow – when you find a trigger in problem state further down the page, you have to scroll all the way back up to determine what the trigger is.

A way I see this implemented would be like the categories in the left-pane of Picasa, where the header scrolls with the page until it reaches the browser-window top and then sticks to the browser-window top, with only the table scrolling.
