Doesn't have a theme or ability to show RSS feeds but... I built an open-source Chrome extension I call SwiftTab for creating a custom page of links from my Bookmarks Bar (or a folder named "_Swift") https://chrome.google.com/webstore/detail/swifttab/poikmgend...
This is an app I made for breaking communication barriers. It's a simple, yet powerful idea. Use icons to communicate with anyone, regardless of which language they speak. The UI is simple enough that my three year old can use it. The UI has zero words, so the UI is internationalized out-of-the-box. Let me know what you think. All feedback is welcome. Positive or negative. Thanks!
