In a wiki page that contains a task list, I would like to be able to view who completed the task and when. This could be in a simple tooltip or displayed parenthetically next to each item or it could be configurable on a per-task-list basis.

I know this information is in the page history but I would like the information to be at my fingertips.

Our use case is that we will have daily checklists for certain roles or departments to run through. Each day someone will make a copy of the master template task list. People will then run through the items checking them off as they complete them. A manager will then review that everything got done and the manager will want to be able to see who did what and when. Similarly, if multiple people are collaborating on completing the checklist they'll want to see who did what and when as well so they can communicate about the things that got done.
