In admin, the ability to view products "by category"
I would like to click on a category list and call up all its products and edit them
eg say I want to change the price of all T-Shirts in the T-Shirt category. The way I would do it now is to name all T-Shirts starting with T-Shirt so I can use search.
But it would be less limiting if I could search by category.
With products that belong to >1 categories, I suppose we show them in all the categories it belongs to.
