RE: Discovered CAD
Bruce, I just went through an upgrade. What I did was turn on any toolbar that looked remotely useful and then closed (by clicking on the x) any window that was overkill or a duplicate. Different views are useful, but that space is better used for the long snap and line menus. Aside from trimming and stretching, most other items are easily accessed from the pull-down menus.
Oh yeah, don't forget to dock the menus by dragging to one side (or top,bottom) of the drawing window.
