About the Sidebar Improvements

At "On Market" I would add an indicator showing the difference in price between my products and the best market price. For instance, if I have the best offer at the same price with other offers, i would get a 0 next to my products. If my price is bigger than the market with say, $0,08 I would add a +0.08. If my price is lower than the next offer and I'm alone at that best price level with $0.08 distance, I would have a -0.08 sign.

This way I know immediately if I need to go to my storage and adjust the prices of my products.
