I just installed your add on and here are my impressions :
* the "add your recipes" ui is not very functionnal if you have too much recipes to add. Not to mention that if you don't know exactly what a name refers to, you can't check with guildcraft what is the item associated. By the way, thanks for the "add everything" button.
* the search ui in the /gcb should be your main focus atm : I think that you should at least provide the same search engine than the one provided on standard wow (when you hit something, it searches within the components, not solely in the names, and I would like to be able to search by type (for ex. in leatherworking i would like only the "head" to be shown etc.))
