Since the form seems fairly rigid (not customizable), it only seems geared toward quick edit of qty/discount. The problem is that the product name length is too limited.

Suggestion - Why not offer a 'simple view' toggle, so that one could just review the selected products, qty, discount and amount (drop off space for base amount, suggestions, properties, etc.).

This could be used for quick review (so one can actually see the name of the product) and clean up (such as to delete).

OR, instead of having everything cramped into one line, list the Product Name, Properties, Price Per Unit as one line, then in a second line (tabbed over), show the Qty, Discount, Extended amount, etc.

The main issue is that the Product Name length is way too short.

Alternatively, just make the grid properties (on the form) allow for expanding to use more horizontal space, providing preference to the account name to extend longer).
