Hi all, I think we can remove following preferences: decorateBrowserButtons, menuButtonInToolPane, optionalButtons and smartUpdating. decorateBrowserButtons : always true menuButtonInToolPane : always false optionalButtons : always true smartUpdating: always true what do you think ? Cheers Alain decorateBrowserButtons "Governs whether certain buttons, such as the Inheritance button, should bear colors that provide user feedback on their applicability" menuButtonInToolPane "when true, button panes in the various tools will sport a button which brings up the message-list menu" optionalButtons "If true, then optional buttons will be used in certain standard tools, including browsers, message lists, fileLists, changeLists, and debuggers" smartUpdating "If true, then morphic tools such as browsers and inspectors will keep their contents up to date automatically, so that if something changes anywhere, the change will be reflected everywhere."
