Was something I have been musing on. I'm sure most people have multiple storage chests laying around their homes with various items stored within. When we begin sharing our home out with friends and guildmates, wouldn't it be nice to be able to get a basic idea what is in each chest without opening them?
So my suggestion is simple, create a tool tip on mouse over for chests, with the ability to set the name within the chest itself, and maybe even select a generic image. Created a basic image for reference below.
