The controller (used through LambdaControls) can not scroll through the list of Waystones in the interface. Easy fix would be to add a button for scrolling up and down through the list (maybe optionally?) as well as the scroll slider. This would be awesome.

I have since looked at the issues page for LambdaControls and it seems that it is a bug with that mod and not yours. But It would still be epic if the scrolling could be assigned to a button.
