This popped to mind when I realized I needed to craft a flax flower and I had two hats already in queue.
Maybe we can have parallel crafting slots? Like, one underneath the other. Therefore, two crafts are being made simultaneously and it would save a ton of time.
Instead of 10 hours for 2 sushi rolls, it would only take 5.
I find that the higher up I'm getting, my interest level is going down because I'm waiting so long for items to craft.
