Floating Design Windows

Floating design windows are visible windows that float over the workspace, as shown in below Figure:

Floating windows are like typical application windows in that you can drag them around and place them anywhere you please, even on other monitors when you're using a multiple-display setup. In addition to moving a floating window, you can change its size by dragging a border. To make a window float, click the title bar of the docked window and drag it away from the edge that is currently docked.
