The nvassigCntrl window has been changed to make the process of confirming matches more clear. Now, when a cluster is confirmed to be a match with the current cluster it will have a yellow background. Clusters that are confirmed to be matches with a cluster or clusters other than the current one have a golden background. Multiple confirmations among clusters are still allowed.
