Mass Effect's inventory management is nothing short of confusing. While I thoroughly love the ability to customize weapons and armor in the game, I was hesitant to do so. It is just too much of a chore trying to sort out what is what. From the inventory screens, the player is only able to see textual differences between each item. To make matters worse, most items have the same name with only a Roman numeral to distinguish between two items from the same type or manufacturer. While this is bad enough when you are assigning weapons and armor to your squad, it is even worse when you visit a merchant. It is not uncommon to be dragging along 100+ items (which is good, don't limit this!) at which point the list becomes something of a blur to one's eyes. Pictures or icons with the items will help the player to quickly find what he needs and a simple filter on the item types will solve most of the issues when dealing with merchants.
