Regarding actions, you can update their notes and mark them done.
There are now five views for actions including a Today one and Overdue one. The actions can be sorted and filtered to correspond to user needs.
You have now your reference items on the iPhone, for which you can update the notes.
We have also added projects, and you can update all project text fields: vision, brainstorming, organising, purpose and notes.
Next we will concentrate on improving the project hierarchy display, filtering, maybe show actions linked to the project and I would like to have a global find.
Regarding process thoughts, we had lots of problem fitting everything into a desktop screen so we might be able to do something for the iPad but I don't think it will be useful on an iPhone screen size. Also creating new action on a mobile app and sync them back to the desktop will open a big can of worm (Aussie expression which still amuses me).
For me, it is easy enough to quickly process my thoughts on the desktop.
