Currently, if I disable ls-switches, it displays just "(Dired)" on
modeline, as I coded in my patch. When mouse is over it displays
help-tooltip, ("Major mode", "Mouse1 - ..." etc). Is it maybe better to
put ls-switches as a submenu to pop-up menu that appears when one click
with mouse button1? Or how do you imagine the tooltip - to replace one
with help or soemthing else?

I don't know how to add a submenu to that pop-up or a tooltip, but I can
look it up.
