especially hidden views rings bells, chimes with my wish to be able to peek around the corner or to the other side of the building.

one point I would like to add to the list in the above link, would be a metadata assistant. Like a personal secretary or assistant sitting on your shoulder and whispering to your ear:
-you met this person 2 years ago, his name is xx. He is interested in ...
-this place is rated "risky"by passers-by during last 10mins
-the car behind you has been tagged "road-rage" by 31 persons
-you should take this longer route it has less congestion

We have got so accustomed to googling whatever information we need that it's easy to imagine that tendency to drive also augmented reality. Where you can guide the googling by pointing or watching or just being in the right place. Context is everything. As well as location.
