[Lazarus] What happened to TNoteBook?

[Hans-Peter Diettrich]

Since 2011 notebooks are crippled and applications broken:

"Replaces the current wrongly implement TPage and TNotebook with their 
correct implementations."

I cannot see what's "correct" with notebooks *without tabs* :-(

What's incorrect with the previous implementation, based on TCustomNoteBook?

See examples/listview for such a broken project.
