Out of curiosity, Joscelin, what are you envisioning happening exactly when you talk about exiting/entering/jumping from one synth to the other?
What I mean to ask is, what are you envisioning seeing if you tap the command to exit a synth?
Bing Maps with pushpins or some other representation of nearby synths and panos?
One one hand, I don't really want to have to press a key to move to a nearby linked synth.
In Photosynth 1, I could make a synth consisting of multiple walks, spins, pans, and walls and if I was in a pan in the center of a garden that was surrounded by six nearby spins, I could just click on one of the quads from those nearby synths to swoop over to it.
On the other hand, I'm a firm believer in having a way to do things with only keyboard, only mouse, only touch, only voice, only joypad, only motion (Kinect), etc. so in that sense I agree there ought to be a keyboard shortcut to move to another synth.
