Yep (well, windowed can be left up to the window manager, but sizing hint is nice).

It would then be nice to combine these to support either a string or an object (and not to go deeper than one level of nesting, otherwise it gets unmanageable):

 "view_modes": ["fullscreen", {"view_mode": "floating", "min_width": x, "min_height": x, "max": x }]

It almost feels like we are redefining CSS here :)
