Miscellaneous items:

* Are you aware of the "EXPORTLAYOUT" command in A2009? Create a new drawing file of what is "seen" from a single layout.

* If you create 3D models are you aware of the "FLATSHOT" command which creates a 2D projected view on the World UCS XY plane.

* Layer Manager - Are you aware that you can use the old-style layer dialog box instead of the 2009 Layer palette with the system variable "layerdlgmode" and toggle between 0 and 1. On some system have the new-style palette actually open can cause speed problems as can an undocked command line palette.

* Right click over the Quick Access Bar and optionally turn menubars on and/or toolbars.
