Seems that they are working on a good release in the near future. Overall, I am impressed. I was using ToDo, which is good. But what is killing me with all these GTD apps is that they all sync with different services, and if you are not careful, you'll get multiple entries with so many different folders that you don't want because you synced a new app before you erased all the folders in there, and next thing you know every app has gone to hell quickly.
At least for me, if you can follow that.
