Good grief man...shouldn't your software be open to all possibilities? The more modular it is the more powerful it will be.
This is simply, removing the requirement for the variable to be filled out (nothing more, nothing less)...this wouldn't screw anybody up or their legacy code.
I bought this software about a month ago...I am surprised you are not receptive to such a simple fix that furthers the robustness of the product.
