TwitterApp is a tool built by Twitter fans for Twitter fans. A Twitter account is required to use the app. With this tool, links clicked on in your Twitter feed will open in the app's built-in browser. You can create a keyboard shortcut to open TwitterApp. To avoid it from standing in your way, you can set the menu bar panel to float on top of all windows.
