I may be confused because I've been using the Starlight skin, but when I used Viewer 2.3, the names in chat were always in a different color from the text, while in this beta the names are in the same color as the text. True? If so, I'd request that the 2.3 style be made available as an option (even if just for skinning); it lets me scan through a chat for particular names.
(On second thought, this may already be possible, so I should have started by asking if there's a way to do it, before making a feature request for it.)
