[Feature Request] Multiple User Support

[l0nax]

Feature description

It would be nice to be able to work with multiple users.
For example, if I have two (independent) reviewers they need to say – independently of each other – if they are reviewing and (later) to approve.

The current behavior is that one person overrides the status of other persons.
