option to open crafting window with all expansions collapsed
The option already exists to expand/collapse all if you are in the Groups tab, I would love it if that were possible in the Crafts tab.
Otherwise, if the settings allowed you to select having everything collapsed when opening a crafting window that would work too.
I personally would love it if the crafting window remembered the collapsed/uncollapsed status between sessions. If I am only focusing on current expansion crafts, then I want the older stuff to stay collapsed not be expanded every time I open the window :)
