If I am in an individual project task list (clients -> specific client -> project -> tasks tab) and click on the comments column, I can see the comments but I can't tag reply my project collaborator in this table view. The only options I see to tag are myself and an approved moxie implementor. I can only tag my project collaborator if I open up the task detail page. In the task detail page as tagable people I see myself, approved moxie implementor, client contacts and the project collaborator

I want to be able to tag my project collaborators in the task table as well, otherwise this feature is not very useful to me.
