This is a bit of random request, but one that I think may have merit. I'm not sure how it would be implemented either.
As a feature, I think it would be valuable if you could turn on a requirement for users to justify their accessing certain private documents (this could be indicated by a security tag, for instance). For example, if I try to open ConfidentialDoc123, LF would prompt me with a window: "Why are you accessing this document" and I would have to provide a brief reason as to why.
This would track why users are accessing records and would deter/track unjustified access.
