The NagVis maps snapin can be configured to be rendered as tree (by configuring the global setting "multisite_snapin_layout" in NagVis).

The fold arrows rendered in the NagVis snapin were not displayed correctly in 1.6.0b1. The rendering has now completely been cleaned up to be working as expected again.

The folding state was never remembered for this snapin which has also been fixed now.
