Navigation bar

[Ayutac]

I always forgot to complain about this one :-)
So we have a navigation bar for the exercises, for example
EiP WS 2014/2015-> Blatt 12 -> Blatt 12 Aufgabe 02 A -> Submissions
when I'm in "Blatt 12 Aufgabe 02 A" or a certain submission, this is displayed and it's good. But when I'm in "Submissions", I only get
EiP WS 2014/2015-> Sheets
which is annoying because I have to select the exercise sheet again. It should be at least
EiP WS 2014/2015-> Blatt 12
if not more.
