I like the idea. The problem is that you're focusing on features you already have, not features you lack. If you don't allow your users to tell you where they see your weaknesses then what's the point?
What about OmniFocus's nested contexts (that don't show in lists if they are empty), search-based location awareness, or reviews (just to name a few from one competitor)? The implementation details are much more important than just checking the box.
Am I allowed to change Toodledo statuses? Saved searches need to be "Partial" at best since the searches are not synced or available on iOS.
I love the product and am/will continue being a pro user, so I hope this doesn't come off too harsh!
