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.
