We know a document can have multiple views, if we want to display these views simultaneously using the doc/view model then
we can use splitters embedded in the ChildFrame or tabs using the CTabView

What I want is to be able to display multiple views with splitters within tabs
Is this possible, it was not many years ago and I used this library

But this work has long be abandoned and does not work correctly with the new MFC extensions classes CMDIChildWndEx
Which I now want to upgrade to using VS 2012.

Any ideas?
