Flatbook can show you who unfriended you, looked at your profile, and more.Flatbook appears as a link under your name to the top left. Once clicked it opens up the main interface. There are now shortcuts to unfriended and profile visitors. Once installed, there is no history yet, so you won't have any information but will in the future.Now for the elephant in the room. One of the biggest use of space in Flatbook is the Feed. The feed is a bookmark manager for Facebook. It comes with a lot of well-known sites and seems pointless. Of course, if MajorGeeks were a link we'd probably think it's the best thing ever It lacks any ability to edit the feed, so you're stuck with what they give you. Otherwise, we think it might be nice to be able to skim all your favorite feeds like this.There is an options link, but at the time of this review, it's grayed out. The biggest problem Flatbook has, it's that it will need to be updated. Facebook does change the code frequently to block apps just like this one so your results may vary.
