Feature description

Hi!

Firstly, thanks for such an active and wonderfully built project. I stumbled upon this as part of my Sunlight/Moonlight experimentation, and it's really become the linchpin in the whole setup.

One thing I notice, I do a lot of causal gaming on an Android tablet, and find it quite fiddly to try and scroll through the games using the scroll bar. As it's a table, there's no controller and no mouse wheel. All I can do is effectively tap and drag.

To make it easier to get through the games, it would be helpful if the main scroll windows could be adapted to respond to click and drag as if it was a scroll instruction.
