Parent and child todo list issue

[victorhck]

Hello!

I have testing your plugin and I like it! I found a little issue.

When you have a Parent list and a couple of child tasks if you mark both as done the Parent is marked as done, that's right. But if now you add a third Child, the Parent keeps been marked as done. Should be automatically be Undone... (IMHO)

The same feature should be if you have 3 Child tasks, 2 done and 1 undone. The Parent is Undone. Ok. But if you delete the Child that is Undone, the Parent should be Done...

Sorry for this mess of Child, Parents, done and undone tasks!! :)

This is a very nice issue you found, but at the moment it requires too much work to do on algorithms.
