Dream, please look into it.

The problem from a technical standpoint is that it would require a client/server interaction every time you craft something.

They would have to change the way items are stored before they could allow us to pull items directly from storage while crafting.

Not that I don't think this should be the case, it would just require a ton of work on their end to accomplish this. Which probably means it won't ever happen.

That already exists. Right click on an item in the crafting window and you can search for it--in the chat box it'll tell you which tab of your/your retainer's inventory it's in.

Can you please SE make it so that we can craft using items in our retainer’s inventory without having to go back and forth to each one of them.

I remember them talking of looking into this.

You can also look at your retainers inventory on the lodestone now.

This answer in the Live Letter touches on the retainer system, and it is most likely also applicable to this current thread:

The server that manages retainers are calling each retainers individually when you need to give orders. So calling four at once would cause lots of stress on the server. As mentioned earlier, we need to place some type of limit on the stress somewhere to get features like glamouring directly from retainer inventory. We’re considering these with the server loads in mind, so we ask for your patience. Additionally, we’re looking into making it possible to sell items directly from retainers.
