I would love to be able to somehow flag profiles (for myself or collaboraters). This would be useful when I need to do more research on something specific and would likely take a while to get back to the profile, e.g. discovered a difference in resources pertaining to the date of birth (and want to mark it). It would be great to get a list of profiles which I know I need to go back to.
At this stage, I print the profile and now have a heap of them needing attention.
