Considering the pain of keep seeing crafting animations and having to be waiting to finish them every single time here is the idea.

Autocraft: So let's say you want to craft all your cracked jewels and you give an order in the crafting station like craft all/or specified amount of cracked jewels and it does the job for you but while it is doing it for you in the background you will be able to play the game as well

Autocraft Order Slots: With the autocraft crafting slots will be less viable to get but here is another idea to compensate that. So while crafting in progress you will be able to give orders (up to 3 orders or so) like let's say while crafting crackeds you give an order to craft damaged jewels next so when the cracked jewel crafting done it will automatically start the next order for you and so on. Those slots going to be purchasable only with plat.

So that hopefully crafting slots won't be losing their value that much since they are making it quicker for you.

Also you can sell them like hotbars so STS makes their profit and players save time from that.
