I go along with a33, here - the green board is not an improvement, and back-steps from what makes w3t distinctive -- with one exception: for the icon-challenged, text buttons in place of icon buttons could be helpful, but these should be an option, config'd. in w3tvars or w3ttheme, and if that, why not go all the way with the option, and give the Previous thread, View all threads and Next thread buttons text values, as well.
In general, though, if it isn't broken, don't fix it, works here.
Thanks, Scream.
