Another Sidebar mockup (tree view style)

[Kevin Funk]

Just had the feeling to post another mockup.
I quite like the new sidebar, but I think it requires too many clicks to reach 
a single item (three clicks (worst case) are needed to switch from one to 
another).

Here [1] is another approach (basically it's tree view style). If that whole 
thing is getting too tall, we could trim each element in height (there's a lot 
of wasted space at the borders anyway). Worst case are two clicks for each 
item.

Greets,
Kevin
