Link Bubble is a godsend. A link you click in an app opens in a chathead like bubble, which can easily be dismissed or shared with Pocket or other apps. It's great for browsing Twitter or RSS apps. Open an article, read it, dismiss it (no longer a cluttered browser with 50 tabs).It does not substitue a full featured browser (no bookmarks), but makes browsing of feeds much easier. Free version only supports one bubble and app at the time, full version is 5 bucks.
