Very clean design - you've put a lot of thought into this and it shows.
I most appreciate the ToDo->Doing->Done implementation. However it does assume that all to-do comprise an equal proportion of the job. It doesn't allow for a list with 10 items, where number 2 is actually 50% of the work. But that's probably not something easily quantifiable to begin with.
One typo I noticed on the files tab (when empty):
"Upload files to share with you team."
Also I couldn't get the photo upload to work on my settings page. The spinner would appear then go back to the default image, and saving didn't help.
Also if we disrupted the ocean currents it may have effect. Apart from killing off lots of animals, of course.
