This is not a bug report but a usability feedback.
The updated ios 7.1 app has the following usability issue:
* Much slower (compared to the older doit.im HD under ios 5/6)
* No longer has those on-screen shortcuts to quickly categorize a task to TODAY, DO it NOW
* Doesn't support scrolling (previous next task) any more.

Because of these, it is a major productivity setback. The interface might look nicer (which isn't that obvious), but the user experience is much worse.

I have a separate post on some of my ideas on what the ios / android app could improve in terms of productivity and usability.
