I have one suggestion for an improvement I'd like to see in the mobile app and the web site. When I check something off my list, I like to see it disappear from the list immediately. In toodledo, it is necessary to refresh the screen in order to have this happen. Most apps move an item to the "done" folder right away. I think this would be a big improvement.
I echo the request for indented sub-tasks, but also want to give a big thumb's up for the aesthetic redesign. Love the new look!! I would like to see the web site version get a similar aesthetic facelift! I'd also like to see a native app for android.
