How do I reset Top Sites in Safari?
I am using OS X 10.10.4 (Yosemite) on my 2013 MacBook Air. I had Mountain Lion before I upgraded, and on Mountain Lion there used to be a "Reset Safari" menu item where I could select items to delete (such as cache, cookies, Top Sites, etc.) The reason I'm asking is because my Top Sites are cluttered with random websites that I visited, but they are not really ones I access frequently for some reason, so I want to reset it to defaults to make it neater again. What should I do?
MacBook Air, OS X Yosemite (10.10)
