AW Build 1183 brings a much wanted feature to AW:

Build 1183
23rd Nov 2010 beta
Objects loaded through a group file from local disk, will be selected as soon loading has finished.
Loading objects from disk has improved by 6 times in speed, and the loading progress is displayed in the chat log.

In summary, not only do AWGs load faster, but they built in a selected state. No more needing to build directional variants of all your AWGs!
This sounds like a good excuse to finally update the AWGs on the academy
