Support all those ideas. Personally I tend to keep my bank pretty light but it would be really helpful to be able to look at the various categories of items you have in the way you describe.
Personally I wouldn't be in favor of charging a fee for "GE running" but if they did I wouldn't mind it either...I get the impression that this would be used mainly to dispose of junk and not stuff like rares.
full support. Can't think of negatives(that's saying something if u compare this post to my others on the forum group) i really like the idea of a runner they should make a quest item related mini bank. otherwise i love it.
Support. I like the idea and even the idea of the GE runner... in fact I had thought of something similar but your idea is much more advanced than the one I had so I really love the idea seriously good job.
