One of the things that has been a long-standing pain here is that if you run more than one blog on WordPress.com it’s pretty difficult to switch between the dashboards.
It’s actually easier to leave your dashboard and go to your blog’s home page, so you can use the admin bar to move between dashboards. Countless mouse clicks have been wasted doing so.
No longer! Now if you have more than one blog you can hover over the title of your blog in your dashboard and it’ll show you a drop down with all your other blogs. Clicking on one will take you to the same page in the other dashboard, with one click! Mice around the world will breathe a sigh of relief.
