With the introduction of the crafting system though the amount of time you will spend in front of crafting devices went up alot. So for those who want to speed up this non-challenging game mechanic I propose an option to turn off the 'crunch' animation of all crafting devices. This would allow players to click something quickly multiple times without sitting around waiting for no real purpose.
As another related crafting UI improvement I suggest that item decon, shard construction, item construction, and shard transmutation all occur in the same alter. Three simple checkboxes added to the shard construction UI with the other three options would allow easy sorting still, but speed up the time people spend crafting.
As a final note on upgrading the crafting UI the ability to turn on a filter option that displays recipes based upon what is in your inventory (and bags) that you can fully construct would be very useful and speed up crafting even more.
