 ## Known issues
 
-Some Gnome status / application bars do not respect the "remove from taskbar X11 atom (_NET_WM_STATE_SKIP_TASKBAR)". So Thunderbird stays always visible when minimized.  
-- Ubuntu Gnome (red status dot stays visible) Please be aware that the icon always will be visible because it is a launchbar also...  
-- CentOS Gnome (Thunderbird stays visible in the taskbar)
