There are two tickets that follow on from Pharo 3 beta bug fixing I was involved with, but I don't really know the UITheme architecture well enough to follow up further. Others seem to have got quite involved with themes and I wonder if someone might kindly be interested in following these up. Otherwise I guess I'll just close them as abandoned. https://pharo.fogbugz.com/default.asp?13118 Clean up the mess in UITheme hierarchy https://pharo.fogbugz.com/default.asp?13121 Cleanup Colors & FillStyles for UITheme & PluggableTextMorphWithLimits cheers -ben
