I like how it allows me to easily create multiple products in one catalogue, with different prices for each product category (and subcategories).
The interface could be improved - sometimes items are not displayed correctly when using drag-n-drop mode; also there's no way of editing information after creating an item or attribute value/category combination within this part of toolbox view. It has been very helpful so far because we can quickly build our own CATALOGUE PRODUCTION SYSTEM from scratch without any help! We have all kinds of categories such as clothing sizes / styles etc., which makes building up stock easy for us at all times during business days & nights hours etc..
