From a design point of view (I'm a designer), I think you went overboard. When I am working I don't want anything getting in the way between me and the list items. In your analysis of your competitors, for Workflowy you said that it's confusing to have many nested lists (I'm paraphrasing here), but the thing is—I find WorkFlowy way more logical than your service. The nesting is a visual guide for the user, letting them know where they are within the tree. At first I couldn't figure our how to check items off, but then I noticed the little tiny “x” to the right, dangerously close to the “>>”. Feel free to beef that one up, and space these two out. Also, apparently I can't check off the last item in the list? That's strange, but it might be a bug. Lastly, I love the help overlay, nice!
