Settings
In the settings you can adjust some options for the behavior of RxLauncher.
There you can show all applications by checking System Applications (and turn them to user applications if you need, by going to their specific app settings), and you can also show again all hidden apps.
Use the Add new Web App/URL field to add shortcuts to your favorite web sites and applications. They will be added with the other applications, and you can customize their names and icons too.
