Requesting the ability to turn on a debug mode for the addon (by typing something like "/atsw debug") which would display all debug messages in the program on the screen when the addon was used.  

Since this is such a large program and the problem of locking on opening at high craft levels has been an issue for well over a year (maybe two years?), it would be nice if those of us who still rely on the addon could try to help pinpoint where the program is getting hung up.  Additionally, it would mean the author wouldn't be required to level all crafts personally in order to test them and locate problems.

Having a specific debug mode would also allow the author to leave debug messages in the program at release, since they wouldn't be visible unless someone deliberately activated the mode.

The abandoned RecipeBook addon has such a debug feature in it and I was able to track down a few of the issues and repair them despite only sketchy knowledge of LUA.
