hide unkown / unbekannt ?

[Oliviander]

Hi Simon,
after some time when I left Minimserver running without
myself always tweaking around, I am back playing with Minimserver once more.

And so I am coming up with a question:

Is there an option to hide the -unbekannt- search entry
(I guess it is -unknown- in the original language)
for files that don't have a tag of that name ?
