*Case 1 :*
In VS 2015 Document docking behavior, Document windows can not be moved to Auto hide and dock. Document windows can only be float and back to document docking child. Same behavior needs to provided for DockingManager.
*Case 2 :*
In our current implementation DockingManager Document Docking behavior is working based on Visual Studio 2008. Current functionality is when dock hover action is done on Document Container and dock the control, it will be added as dock child.
We need to improve this like MS Visual Studio 2015, in that dock hover action is done on Document Container and dock the control, it will be added as document container as same or different group based on hint. At present there is an option to do this using programatically, now this behavior need to be provided for DockingManager.
As some customers will expect to use the old DockingManager behavior, we need to provide option to switch between existing and VS 2015 behavior.
