As the Stack Exchange family of sites grows bigger every day, I find it difficult to quickly find those sites that I care most about in the Stack Exchange menu at the top of all the sites.
I'd like some kind of indication (perhaps highlighted, or an icon) on that menu, so I can find more quickly.
I'm guessing that the pulldown was originally intended to allow you to navigate at a glance, but as it grows more complex, it becomes much more difficult.
Based on @Grace's response below, I believe that one possibility is to add a "My Sites" submenu next to the "All Sites" submenu. I realize the benefit of having all sites listed, but sometimes I just want to get in to do what I need, and get out.
