Depending on your chosen settings, Apps can automatically start with the Menu and the Dock visible or hidden.
MenuAndDockless can save and restore those frames for different display setups - meaning the annoying re-organizing of windows at work and at home is now a peace of cake.
You can also use MenuAndDockless to 'arrange' windows on the fly by either use the menu item or your own applied shortcut, make them floating or enter a fullscreen mode that does not automatically create an own Space - which means, drag-and-drop and Expose will still work and there is lots more you can do with MAD...
