It works especially well if you use the eProductivity mail template from eproductivity.com.
The app pulls all your unfinished ToDo items (or Actions) from your Lotus Notes To Do.
Stores these in a local database for easy offline browsing. It lets you select which Context (Category)
from the ToDos to display.
You can mark a ToDo item as Done by long-pressing it in the list. This Done flag will synchronize to your Lotus Notes
To Do when you activate synchronization.
You can create a new ToDo item and it will synchronize to your Lotus Notes to do when you activate synchronization.
The app lets you toggle whether you want to see all your Actions or just the ones flagged with the Today flag. You can add or remove
the Today flag from an Action by long-pressing it.
Note that a FAQ is available from the developer website.
