  [ Albert Astals ]
  * Minor optimzations Add const & to foreach to save copies of
    "complex" types Remove initializations of QStrings to "" since they
    do nothing Return QString instead of "" since its faster Pass
    "complex" types as const & instead of copy to functions Not an
    optimization: Added const qualifier to two functions .

  [ Lars Uebernickel ]

What if it just bounced slightly into view during the transition? Much
like when you tap on the welcome screen, the dash or screen bounces into
view a little. It would keep it consistent with the discoverability of
these other features, and not get in the way after I've already learnt
that there is a toolbar on this or that page.

With the focus on content, I don't see why I should have this toolbar in
my face everytime I access a page, I'm going to have learnt the toolbar
exists here after the first 1 or 2 times it happens, and then it's just
going to keep doing it everytime anyway.
