Just got WooCommerce and I love it. I would like to suggest an improvement in one area though.
I think it would be a good idea to show 'weight' on the dashboard page that shows the list of products. Right now the features that show up at my fingertips on that main page are: Stock, Price, Category, Date, etc.
As it is now, if I forget to put a shipping weight on even one of my products, the shipping won't come out right and I won't even be aware I haven't entered a weight for that particular product without opening each and every one of my products and looking to see if I have listed a shipping weight.
If you were to list weight on that main page, it would be very apparent when/if I forgoteto enter a weight.
