[Feature request]: refresh button

[kopach]

Current behavior:

1. user enables Show files unreviewed option
2. user marks new files as reviewed
3. now in order to hide newly marked as reviewed files user has to disable and enable back again option Show files unreviewed

Requested behavior:

1. on step #3 in order to get newly reviewed files be hidden - user clicks refresh button

Do you think, that would be possible to implement? Of course, refresh button could refresh everything else, not only show/hide files but this is what most interesting for me right now
