Slick app but not without problems

2Do is good enough to have converted me from OmniFocus, which I have been using previously.

I dont know how it was in previous versions but the current incarnation is slick, well designed, intuitive, and responsive.

Whats preventing me from rating it higher is the presence of a few bugs and omissions:

The most critical bug actually results in data loss. I created a list called Projects, and created a number of tasks within it. I then decided to create a sublist within Projects and tried moving some of those tasks into the sublist. When I did that, both the sublist and the tasks disappeared; nowhere to be found. This happened to me on two separate occasions.

Another bug (minor) is that using Quick Add when one of the Lists is highlighted does not default to my Inbox (default list), contrary to what the description says in the app Settings.

The drag and drop feature for tasks is great, but doesnt seem to work for moving tasks into sublists. An opportunity for improvement.

And, last but not least, where is iCloud or iCloud Drive support? Currently 2do recommends Dropbox for syncing because their other methods have various caveats and restrictions. But not everyone has or wants to use Dropbox. iCloud and iCloud Drive are part of the iOS and OS X ecosystem and they should be available and recommended before any 3rd party method like Dropbox.
