Great idea, but can't tell if it's working. The status line in the menu says $22.64 donated—exactly like the screen shot above. Is that the amount donated by all users? Whatever it is the amount does not appear to change. Also, it would be nice if the donations could be set to go one or more of the four charities by default so that one needn't do it manually. This setting will be especially nice if the list of charities grows. Links to the charities' websites would be nice too. Even in "faster" mode Compute for Humanity has a very low impact on my 2011 MacBook Pro.
