window-list-menu without class-grouping

[Maurice <mauricex gmx net>]

Hi,

is there any hidden option or something to show all windows in the
window-list-menu at once, without these class-sub-menus?

If not I will try to write my own window-menu.

Thank you for any hints.

btw, the search-engine of the list-archives seems to be broken.
Whatever I search for, it gives me no results.
