Seriously. Developers. Build this.
I can get behind all of this, with the exception being that I *do* care about the past. I, too, want a calendaring app to focus on the here and now, and taper the level of detail of future events by time-proximity, it should still retain the ability to easily jump back a [day|week|month]. It shouldn’t need to be said, but I wanted to point it out none-the-less.
