Running AutoCAD 2000 but disappointed in not having tabs like Microsoft Excel does to easily flip between drawings. It is cumbersome to have to go up to the windows menu and select the drawing you want to view. With a click of the right mouse button you can rapidly switch between Multiple open drawings. Drawing tabulator is a dockable toolbar that will remain visible at the top or bottom of your screen see the screen shot. Download the trial version today and see if it helps you.
