Color recipe item icons relative to the status of your alts' crafts. (for example, a recipe that one of your alts can use may be colored green)
Broker that lets you view your alts' crafts. (using craft links)

Open the options dialog with '/boc' or '/bookofcrafts'

Credits

My big thanks to Ayradyss, maker of "RecipeBook" addon. I've been a first user of this add-on, but found myself in need of something different and I have developped "BookOfCrafts" (also at this time, RecipeBook development was stopped). This is thanks to "RecipeBook" that I started to get involved in Add-on development.

However, there is no competition with "Recipe book" and Ayradyss. Perhaps you should check also this add-on as it is a great add-on that you might prefer for its different features.

Special thanks to Lombra who has fixed the "Bind on pickup" problem while I stopped playing Wow for 8 months
Special thanks to Bburt for his overall help
Special thanks to Ghandi and Ayradyss for German translation
Special thanks to Lisurc a.k.a Lisenrak Sargeras (European server), for maintaining and tweaking BoC while I was away
Special thanks to ArtureLeCoiffeur and Tezaro for their bug fixing skills
... and my thanks for all of you for your feedback
