Link tasks, so that once a task is done, it shows the next task in the series

Just like Evernote have an outlook addon that let you take an email and directly assign it to your app. Allow to set tags and schedule

This would make the app a perfect projectmanager for me. Its the only thing I miss.

A new Focus area for tracking tasks that have been assigned/delegated to someone else, along with the ability to track who it was assigned to.

When I create a project, I'd like to have a notes field to keep my random notes regarding that project (desired outcome, napkin brainstorms, etc.).

Give option to filter by Due date by either specifying date/range or number of days late range

It would be useful to have a notification on the iphone app of the number of 'todays' to do

The ability to see all the tasks which have not been assigned to a project grouped together would be helpful.

This would allow a way to review projects that need a "next" action. Keep projects always moving forward. Better able to focus just on tasks and not constantly reviewing projects just to see if I need a next action

An export creates a mix of all Focus areas, home + work + club etc. I only want to see one set of data, not work tasks mixed up with home tasks.

Add field for priority, thus we will be able to sort today this way
