Hi, this is a patch to make the look and feel of Tabbed layout's tabs similar to the Ion3 tabs. Hope former Ion3 users are going to enjoy. Ciao Andrea Fri Jul 6 14:59:58 CEST 2007 Andrea Rossato * Tabbed: added more configuratio options It is now possible to configure active and inactive border colors, and active and inactive text colors (i.e. tabs are now very similar to Ion3 tabs: former Ion users may appreciate).
