Scrolling of the scenarios

[marcelloh]

If I have more scenarios then fit in the window, there's a scrollbar.
If I put an extra scenario in, it is often on the wrong place positioned.
When I position the new scenario downwards (with the hand), it scrolls out of my vision. So I have to scroll down, just to see where I left it, just to scroll it some more.

I suppose I want autoscrolling (for reaching beyond the visible bottom and also for the visible top)
