I would like to see the ability to pre-define sets of pictures as galleries, to simplify changing which sets of pictures are shown.
As picture galleries accumulate, a master gallery selection environment could be developed which might consist of simply a long (perhaps autoexpanding) hallway of virtual doors to allow access to each predefined gallery. The user-supplied gallery name might appear on each door in gold letters.
The master gallery selection environment would technically be simply a 3-dimensional menu system that would allow the viewer to remain "in context" between galleries. The main backwards-compatible issue I can think of would be adding the mechanic of leaving any given gallery to get back to the virtual hallway. A virtual "exit" in each gallery theme would simplify this, but raises the question of the need for 2 doors - one that exits back into the virtual hallway to find another gallery, and another to exit the gallery completely - but that is currently accomplished with the escape key
