Hello.
First of all, I think Doit.im - best todo-manager ever! :) It's a lot of function.
But I have really big trouble with one thing. When I creat task and in it make sub-task, I can't see it in main list of todo. When I have a lot of things todo, I forget, that in 1 task, can be more subtasks. I write something in description, to see it. Can you add some little icon to tasks, that have subtasks. It will be really great.

With bad english, but with love from Russia :))
