Nice app but lacking due date

I thought it would be like a plain text version Taskpaper. However, this app is to simple.
- I can not change the Dropbox todo.txt file name.
- I cannot set due date for tasks. (Really basic function for a todo app) I thought about using due date as tag,but that was not so ideal and also not what I really want.
- sometimes it crush also.
- also it seems they dont update this app so often.

Add due date and I will give it 5 stars.
