I have not been a fan of RLV until recently, not the viewer the feature. A friend formerly from Land of Nor has been showing me how it could be used to improve roll play and combat games. I was impressed and have sense been spending more time paying with it.
Marine Kelley posted about the recent update to the RLV viewer: RestrainedLove Viewer 18.104.22.168. Marine explains some of the problems integrating the CHUI changes to RLV. It took a couple of months to find bugs and resolve them. The fixes are done and a new version is released.
