todo lists
You can now use a specialized 'todo' list template accessible via the 'Go' menu. Your todo list behaves slightly different to the rest of your lists. Firstly it's anchored in one spot (http://zimoutliner.com/list/todo/) so you can bookmark it. Secondly, it's a rolling list, which means if you check off items in the list using the checkboxes, they will be scrubbed from the list the next time you load it up.
The todo list screen is a place to keep your next actions as they come to you and erase them as you get them done. I find it useful to prioritize my next actions in a vertical order on this list.
