which KMainWindow?

[Alan Ezust]

I'm having a difficult time understanding which MainWindow class is
being used where.
In particular, I use the "tabbed pages" mode, which has some dock
windows with tab panes inside them.

Which class is that?

I noticed a bunch of "mainwindow" classes which have no documentation
on the top.
What is SimpleMainWindow? If DMainWindow is the "simplified idea
mode", what is the "full idea mode"?

What is the classname the docked tabbed widget full of tool views?
Where is it created?

Also, is there a tool or a way to export and import the shortcuts in KDevelop?
