I have a problem with the naming "Issues"
In my humble opinion, I have the following definition:
ISSUE = Something that is a potential problem that need to be tracked. An issue is not assigned to a person.
PROBLEM = an issue assigned to a person that will come up with a solution to the problem.
When you use this functionality for adding actions in a meeting it seems a bit strange to assign an issue to a person.
In that case I would like to assign an ACTION to a person.
I now that you will not change your issue management system for this. However you might consider these aspect in any potential next version of your service.
