Add in "splitstage" as a feature to sidestage

Registered by kevin gunn on 2014-04-28

this blueprint is meant to track the feature of "splitstage" for the sidestage/mainstage views. "Splitstage" refers to the tablet special case of having the mainstage application reflow to the visible area defined by the device left, top, bottom & the left edge of the sidestage surface. This is different than the "overlay" mode of sidestage available today where the sidestage application persistently occludes some portion of the mainstage app.

Whiteboard

design questions:
- must all mainstage applications support splitstage ?
- in the event the user attempts to place in splitstage mode, but its disallowed, is there a notification? or simply a visual highlight/gesture bounce ?
- is the default of opening a side stage application selectable in user settings between split & overlay ?
- besides the user selecting to enter or exit splitstage, what other system events may cause this? (e.g. rotation, special spread navigation case?, quitting app from running apps in dash? or if there's another sidestage open does it simply replace it? )

(?)
