* Fixed a bug which kept objects in tree view opacity low even after all of the filters are cleared (this was introduced a couple of builds ago)
* Fixed error when deleting nodes that have composite inputs from a view and then undoing the operation

* Fixed: Delete button sometimes stops working inside viewports if ZK is open (ZK didn't release its delete user when view was closed)
* Other minor internal improvements
