I actually was thinking about an idea where you have built in "macros" to the crafting system, call them "patterns" or "blueprints" or something
Where you can build a set of instructions to follow for quick synthesis or whatever. I'm not sure how doable or balanced that would be though.
Would at least be nice for practice synthesis to let you go back if you screw up, and maybe show you a list of the actions you've done in the synthesis or something. Simulation sites like teamcraft are cool and all but it would be nice to just have that sort of functionality ingame to not have to rely on a website.
