Love this plugin @onlyME.
Only one issue and one suggestion...
on mobile view, (iphone) the thumbnail messes up the text pagination. Reducing the size of the thumbnail makes no difference.
As for my suggestion, without the plugin the forum has a dark icon for new messages, and a lighter greyed out forum for no new messages. Is it possible that the thumbnails can be lighter greyed out when no new messages and normal when there ARE new messages?
At the moment it's a lot harder to work out which forums have new messages....
Also, when you clicked the darker icon it made all the messages read, and then went lighter.
These changes would make the plugin perfection for me....
