Second click to close Alerts

Probably just habit coming from years on Facebook, but it gets annoying that once I click alerts and read the notifications, I click the tab again, and it sends me to the alerts page. On facebook when I click notifications then click it again it closes the drop down box. Now I understand this is not facbook, but it would just be nice to click it to close the alerts tab. There is a clear "Show All" at the bottom, and you can click the "Alerts" title at the top of the drop down box, so there really isn't a need to have it as it is now.

Other people if not everyone, uses facbook, so i'm sure i'm not the only one that unintentionally opens the alerts page when I meant to just close the drop down box.
