So basically I think it would be great if we could all rename containers, this would be great for merchants (and other people who often use them). It would greatly help because you'd be able to sort things into categories. When I'm merchanting on my merchant alt, Eyantar and someone buys something, I have to go through all my containers to find that one item, it would be so much easier if I could have my containers named in categories.
The new name of the container could probably only be seen/noticed by the player who changed it.
