464996 Oscommerce 2.3.1 minor changes...

I have a new shop installed running Oscommerce 2.3.1. It is somewhat adult in nature. The site is [login to view URL] What I would like to see happen is to change the way the store functions so that customers can only see the Category layout. I want every product to be listed as if in category view. Widen the layout so we can fit the description in as well. When the customer clicks the Buy button, the item gets added to their cart, but they stay on the same page so they can select more. Also, I don't want any customer to have to register to make a purchase.....when they go to the checkout page all they should have to do is just pay. (I have eprocessingnetwork already setup and it works). I would like however a option if the customer would like to register so that they can make more frequent purchases in the future, but this should be set up as an option - like an Ewallet. I do want to capture the customer email address for contact purposes. All new products that get added to the catalog always get placed at the top of the list so that customers can see what's new. Also, for some reason there is no "Continue Shopping" button at checkout...if that could be added in case customer wants to add more items. And finally, all downloadable goods in this shop have to be in zip file format. Can we make it so that I can have the customer just download the file without being zipped? That's it! Scott-
