The only way I've found to navigate dates in the agenda is by clicking the "move one week" arrows. A common use case is "I need to schedule an appointment 8 months from now, I wonder if I have any conflicts on that date?" -- having to click the advance button 35 times is, um, well, you get the idea. I've tried using search for the date, but can't seem to get that to work, which makes sense as I think it's documented to work only within the current week. Any other way to navigate to future dates?
At the moment there isn't a better way to navigate to a particular date. This is something I need to investigate and add in a future release.
