Action Item List

It would be very useful to be able to maintain an action item list within the project platform and assign individuals with in the project directory along with due dates. Need to be able to track status from open, in progress, closed. Need to keep all action items (even if closed) for project history (with an option to delete). As it is, one has to use 'issues' or the quality 'checklist' to do anything, but one cannot track/progress it and there is no option to show a status. One can only delete it when it is done.
