Christoph, Joscelin, and all other users: What are your thoughts about having a separate 'Zoom Out' icon in the upper right corner of the viewer after you've clicked to zoom into a highlight?
I'm still thinking about it, but it feels to me as though I would like clicking on the highlight's circle/thumb once more to zoom back out, since it is what I clicked to zoom in, rather than needing to move to the upper right corner to click the zoom out icon.
I will grant that you could also use the scrollwheel or a pinch gesture on a touch screen or minus key to zoom back out as well, but I'm mainly interested in how this is accomplished via clicking with the mouse or simply tapping with a finger on a touch screen, since that is how one most often enters a highlight.
My general thinking is that most other buttons in Photosynth 2 are toggle type switches.
