Hello, thank you for your work, it's really interesting :)
I've a little problem, I've a principle DocumentPane where I plug some DocumentContent and some DockableContent. There is some DockableContent who contains a DocumentPane.
When a DockableContent (who contain a DocumentPane) is Visible, if I close all DocumentContent (tab) on my principal DocumentPane this DocumentPane (the principal) is closed.
Thanks for your responses.
