I can only tell, that for Kate, the multiple main windows stuff is the thing that caused
the most segfaults in all our plugins (even in my own project plugin), as it is non-trivial to
get that right ;)

The plugins for the application normally don't create toolviews and menus per KTextEditor::View but
per main window.

E.g. the Kate project plugin creates on toolview "project" per main window, the search in files one,
...

That they interact with potentially many open KTextEditor::Document/View's is an additional complexity ;)

With only "one" main window, A LOT of stuff will be easier, in the plugins and in Kate.

At last akademy most people I talked about that did think that was anyway the way Kate works, one process instance
per window.
