The facebook tagline is currently implemented in the facebook application settings, so it can't be changed within the application. However, I just discovered that there is an 'attribution' string that can be added to identify the application, so I will add that to the parameters when making the post request.

You can change the text/border colours and font sizes by changing the the appropriate variables in the main.qml file. I suppose I could add settings for these. Layout changes are fairly easy to make, but you will lose any changes upon updating, and I don't really have time to support users that mess with the source code.

I'm always willing to consider proposed changes to the UI (I know not everything is perfect), so feel free to post examples or make suggestions.

The desktop widget is something I would like, along with the QML video player. If it can be done, and done well, then I will do it.
