I've just released v1.6.0, with the following changes:
A few small bug fixes and feature inclusions.
Introduction of topic thumbnail option. With the ability to display a thumbnail of a topics first image.
A suggestion to @Mike John: The current layout leaves a wide space below the avatar. Although this does not seem to be a problem on larger screens, it should be optimized for phone screen. I suggest Mike to resize the avatar and put it into the title bar.
