Version: (using KDE Devel) Installed from: Compiled sources OS: Linux When dynamic hide is turned on, the Settings->Tab Bar setting is not changed. Hence, when the tabbar is hidden, the Settings->Tab Bar can be Top or Bottom. This is confusing, because of course the tab bar is not visible top/bottom. Adding a Settings->Tab Bar->Dynamic Hide should clarify what's going on.
Changed all this dramatically in KDE 4, tab bar visibility is now set in the profile settings.
