Like 'related products', it I add product B to buy together with product A, When I view product A , I see the combination of products A-B.
Cs-cart should auto set that when I view product B, I will also see product B-A 'buy together'

It would be nice that an administrator or customer can attach files to a comment/note on a particular order. For example, I am running a large format printing site, and I would like to show customer a digital proof, or sample printing before I ship the order. If I can attach file to an order, so that the customer can confirm before I ship, that would be super!

The current format to display Options is horizontal. Previous pre 2.0 version was vertical. Would like choice of format in Admin.

Please provide a multi-item order form where the customer can enter SKU and quantity.

Let the storeowner specify that the sales report should also contain the product option breakdown.

What happen with that great idea CS-CART had in its version 1.X ??
Upgrading CS-CART in the backend we just get permission problems and errors (depending hostings, but usually happens). What about an installable software that upgrades by itself (Apache permissions) with no errors?
This would be helpfull and very interesting.

Here is a module SHIPPING No.1 Frenchis installed on another shop.

Here ar ethe manual and the addon.

Create an option to create private sale events with event countdown timer, email announcements, option to restrict to members or make public. This is similar to gilt.com , ruelala.com magento has this in their Enterprise version as well.

The current vertical structure of the product options inventory page makes it difficult to review and adjust inventory levels. It would be much easier to use if the layout were horizontal similar to the product options variants,

It would be nice if we could email customers with abandoned carts after x number of days. It's kind of creepy, but it may also increase sales. Eddie Bauer does this.

Group order statuses under separate tabs. i.e. New tab, Shipped tab, Backordered tab

This will allow customer to purchase gift certificates and print them at home to give to loved ones.

Amazon has this service (https://www.amazon.com/gp/gc/order-print?ie=UTF8&ref_=gc_lp_preview_tight) and it is very popular.

Customers would have the choice of print, email, or mail.

All image auto renaming according to its category or product name (or choose a option from both). Like if we upload a set of images like 100.jpg, 101.jpg, 102.jpg of tunics. And it is belongs to category tunic. It should rename automatically like this tunic-100.jpg, tunic-101.jpg, tunic-103.jpg. i think this will improve ranking in google image search.

Weird behaviour when using additional currencies...

Base currency is EUR and customer uses USD currency. The item is 100EUR so their order/invoice shows a price of $150USD, the currency rate is 1.5.

But when I change the rate to 1.4, his past 'completed' order/invoices will change the price to 107 EUR ($150USD divide by 1.4). This is incorrect because he paid 100 EUR and not 107 EUR.

All placed orders and invoices should be have fixed amount at moment of placing that order.

This is very usefull for follow-up customer who has not been payed as for reminder to pay by scedule time from placing order. if not paying yet then status invoce change to failed/cancel.

When using Paypal Express Checkout, details for every item being bought does not appear on the PayPal site neither on the customer's receipt of purchase from paypal.

not one by one with adding new field for upload using "+", but upload pictures in bulk, like mass file copy
