Previously the right margin of the scrollviewer was 10 and the right margin for the stack panel that contains all the content was 10. Together that made a margin of 20. Now that we removed the scrollviewer margins I forgot to ask you to add 10 to the stackpanel.
So i updated it with the last commit. From 10 to 20 to compensate for the right margin value that was removed from the scrollviewer.

Thanks Darren!
