Version: (using KDE 4.3.0) KDE 4 has no way to separate the actions in the toolbar by space. In KDE 3 it was possible to archive this by using several separators or line separators. Now this isn't possible anymore. There exists also another similar feature request: flexible separator widget for toolbars https://bugs.kde.org/show_bug.cgi?id=143087 Both kind of separators are useful to improve the usability.
