1) - another product option - 'exclude from special offers' eg store has 100 products - set up one discount for %50 off everything but you have 1 product which you do not want to offer for sale - you could choose to exclude this one product from any offer
2) - option to display to customer the quantity of a particular product which is in stock
3) - option to display the amount of products in a category
4) - optional configuration setting to allow hiding of subscriber box
Also
5) - packaging slips are saved in to file folder (other pdfs are saved into file/import export - is this intentional
6) - new image upload feature - is there a way to delete an image uploaded inthis way? - can't simply have a delete button which could be used to delete any image, it might affect products etc - especially if images are stored outside the database
7) - in admin instead of having a lot of extra .aspx pages in administration ( and a lot of extra resource strings) why not have the descriptive writing from the aspx pages appear as the tooltip when hovering over a menu ? and then remove all the extra .aspx pages?
eg
contentmanagementhome.aspx
bloghome.aspx
shippingsettingshome.aspx
there are a lot of these - do they serve a valuable purpose?
