Ok. I'll think about it more and see what I can come up with.

An impuls idea is to have the variable as a stae: nil, short, long, where nil
will hide ls-switches completely, short will show them shortened and
long will display ls-switches entirely, and tooltip could then be shown
when mouse is over the short version.

I will have to look up how to code this with tooltip, but I'll try to
code it :-).
