When inserting product attributes (new option names, values or prices) in admin, the entire order (id) will change, messing up the view in the product options view before adding items to a cart.
Lets say I enter attributes in an order that I want. They're set. Then I decide to insert another attribute. It will mess up the order customers see and all the attributes have to be reordered. A painfully long process in some instances.
Not to get off track, but it would be nice to have control of the id numbers. Also, if someone picks a blank option or option like "choose," there is no warning that the customer picked an incorrect value.
These are not not critical issues, the main issue is the one described at top.
