You asked for it and now it is available! This update is just in time for Christmas. Work Time version 1.1 includes a couple of the more requested features.
You can adjust the brightness by swiping up or down on the clock numbers.
Because the clock area is used to register swipes for brightness, to access settings swipe left on the calendar or weather section.
You can also now remove specific calenders from listing events in your event list section. Hurray for no more Facebook birthdays!
Have a happy holiday.
