"Try tomorrow" isn't tomorrow

[stevage]

Just a very small long-term gripe about the "try tomorrow" button. Well, a pair of small gripes. :)

First: it isn't "tomorrow" (which is the day after today), it's actually "next day" - because it advances the day relative to the currently selected day.

Secondly, there is no counterpart to go backwards.

Really, there should be "Next day" and "Previous day". And, per #86, those should be on the main toolbar, not in this hidden menu :)
