I imagine most of us use a handful of features all the time, and the rest less often. It would be great if we could select just those submenu options (perhaps click a little star in the nav next to it) and have them saved in a Quick Links section at the top of our navigation (similar to Microsoft Outlook Favourites), so that the menu options we use all day don't need us to expand/contract sections to get to them.

For me, just as an example, the Quick Links would probably look like this below as these are the links I use 95% of the time..

Quick Links

... and then below it all the regular navigation.
