Comment (by godiard):

 Very interesting.
 Some ideas, without looking too much at the code:

 * Maybe you can use set_can_focus(False) in the neighborhood, friends, and
 home views, to avoid them grab the focus. Not sure if that will affect
 keyboard interactions.
 * extensions/deviceicon/battery.py __battery_properties_changed_cb do
 always the self.emit('updated') triggering the redraw, even if the values
 didn't changed.
 * deviceicon/network.py, should check previous states to try avoid change
 color and other icon properties if not needed.
 * Journal: I remember cases where the first time we switch to the journal,
 we see the window resizing to full screen. I don't know why and if is
 needed, and if the next switches do a resize too.
 * View switches: desktop/homewindow.py remove the view widget, add a
 transition box (to show the kid icon anumation), and add the new view
 widget. Not sure if that trigger unneeded resizes. Maybe we can use a
 Gtk.Notebook and just change pages? (And/Or remove the transition box step
 at all)
