Storage Bin Lists Remember State

[vladspellbinder]

I'm not sure if this is a bug or intended but when I collapse all of my storage bin lists then click off and then back on to that bin all of the lists are expanded again. I'd rather they remember if I had each particular one collapsed or not, as this is getting hard to manage what goes into which storage bin as I have to keep collapsing each upper level list to get down to the ones I want most of the time.
