We would really want to implement this in a new mobile HTML5 app for iphone/android devices first.Edo Amin commented
I would like to add another aspect to this request. I actually do like to have online access to the data, but I like to have full control over it, and that would be the result of a Checkvist "offline" mode. Checkvist seems GREAT and totally worth the money as a task outliner, but I don't like that part of the package is that I must use Checkvist's CLOUD. Perhaps I prefer the data to be hosted in Dropbox, or in my private cloud NAS. Also, when I am in my SOHO (which is most of the time) I do not see any reason to have my projects online. I actually found Checkvist when reading reviews on Todo.txt, a model that has no online mode, only offline mode.
