The crafting log is great as it is, but when you're crafting for a specific class it can get a little disorganized. In my experience, I have to search through my log for all the items the class can or would use, then favorite as many as I can. This takes over the favorites section and is very time consuming as I have to do so for each crafting class I'm using.
Instead, I think that all crafters would love to have an alternate mode where recipes are organized by class rather than by level. There wouldn't even need to be a section for each individual class, recipes would mostly be divided up into disciples of hand, land, war, and magic. Additionally, you might want to add a material section and divide some sections into their stat focuses. For example, a culinarian might have sections for DoH craftsmanship, control, and CP.
I really think this would greatly streamline crafting, especially once you're done leveling a craft.
