I've got a DockSite with a TabbedMDIHost in it, and 3 tool windows. I want the tool windows to only be allowed to dock on either the left or right. If nothing is docked on the right, the space for docking takes up no space, but still allows a tool window to be docked there.
Is there a way to force tool windows to only allow left and right docking?
This is the 2016 version of docking (the latest)
