I would love to add a banner to my store - is this possible or in the works?

I have a great banner that my wife has done for the shop - wondering if there is a way to make this show on the shop.

I am brand new to the site - and am getting the hang of it. I really wish there was a product category for steampunk as all of my items fit into that area.

Hi JVSteamyBitsPcs,

Welcome on board! 
You can upload your banner on My Profile page. It's below your Avatar.

To answer your second question, as long as you have "Steampunk" in your Product Title or in Product Tags, people will be able to find your products through keyword replacement - steampunk items.
