Maybe everybody knows this but me, but I'll post it just in case.
Have you ever had a bunch of tabs open, and you want to go back to the Home Page for some reason? Then you want to get back. I used to click Search to open a search tab, and that would get me back to all my stuff, albeit with an extra Search tab open now.
But I just found if you just click Home Page again, it goes back to all the tabs you had open before you went to the Home Page!
