 If it is a global gesture it would not, see your first patch, you can
 cycle in and out of the ZOOM_ACTIVITY level.

 In your patch you are including the Activity View:

 {{{
 _ZOOM_LEVELS = [ZOOM_MESH, ZOOM_GROUP, ZOOM_HOME, ZOOM_ACTIVITY]
 }}}

 If you take 'ZOOM_ACTIVITY' out you can just cycle through the other
 views.

 > - There are accidental presses while doing the gesture: activities can
 be started in home favs view, scroll takes precedence in home list view,
 palettes can be raised by accident.

 Right, especially with the zoom gesture. I say, this is an issue of the
 code. There could be fine tuning to make that better to nearly perfect.
 Not too easy I am sure. Easier if you use a multi-finger gesture of course
 (e.g. two finger swipe).
