Popular Widget

The plugin still works as expected but the support doesn't seem to be very responsive: Last reply on the Wordpress forum over 1 year ago, on the recommended official forum over 2 months ago.
More activity would be great since there are not many comparable alternatives.



Nice plugin, and some support would be great
