So I've only been playing around for a few minutes and have decided I actually quite like it for its simplicity.
However, I have a bit of feedback:
* I don't really like the tasks jumping to the bottom once I set them as complete
* A strikethrough on complete tasks would be nicer than just dark grey font
* The backlog doesn't function as I'd expect. The number seems to refer to the total number of incomplete tasks across the whole project, but clicking it takes me to the index. I'd expect the backlog to be any tasks which haven't been assigned to a goal (sort of like the index is now), then a separate function to show all incomplete tasks across the index and goals
* After adding a milestone and selecting it, I have no idea how to get back to the normal project view with the goals and tasks I have already added, except going back to the workspace view then back into the project
* Oh, looks like I click Backlog to get back from a milestone. The backlog feature now makes a little more sense. Maybe it would be better to have the Backlog link close to or on the milestone bar?
