I like the idea, but...

So you know, you can open your crating log while you have the marketboard window open. Just press the keybind for the crafting log after you open the marketboard - press it twice if you had the crafting log open when you opened the marketboard, because the first press "closes" the crafting log that you had open (it's still open after you access the marketboard, it just becomes hidden) whereas the following press will reopen the crafting log without hiding it.
