Dragging Screens to rearrange and Creating Links by dragging are Buggy.
Dragging Screens to re-arrange is VERY buggy. They become subscreens when I don't want them to. I have to use the little green arrows at the top of the section as a workaround.
I'm also having issues creating links by dragging to the screens - it will let me create a link to some but not others - I don't understand.
