Aren't the recipes already in order of their level within the 5 level sections? I'd assume that they'd stick with that, so all you'd have to do is look through the section for the class your crafting for and scroll through looking for the level your working on now. It's already divided by level with a ridiculous number of subsections that are hard to work with, and searching it now means scanning each and every tooltip to see if it's usable for the class you're working on.
Unless you mean that the list would contain recipes from every crafting class; that's a bit overkill, don't you think? The recipe book is already divided by crafting class so you can actually craft everything in that section with your current equipment. I'd think they'd wanna keep that and just replace the level division with target disciple of ____ division for this alternate mode.
