Without A Net: "AutoCAD 2010 Free Bonus Tool Drawing Tabs
In case you have not seen this on Shaan Hurleys blog Between The Lines, I thought it would be useful to mention this great little tool, MDITabs.arx that allows you to quickly switch between open drawings.
MDITabs for AutoCAD 2010 - Download Now
To install the utility you extract the appropriate ARX for your version of AutoCAD 2010 (32-bit or 64-bit) in your support path. Then use the AutoCAD command APPLOAD to load it, and add it to your start up suite so it loads each time you start AutoCAD 2010.
As Shaan says in his blog, this tool is unsupported and provided as-is.
This tool is also available for AutoCAD 2007, 2008 and 2009
