Number of personalized Coupon characters

Hi Seyi, I was wondering if it was possible to enter the possibility to choose the number of characters of the coupon generator.

For example, 
in the Tools > Gift Certificate Product > Coupon Code section, together with the 'Prefix' and 'Suffix' entries, the field 'Exact Character Number' or two fields 'Minimum Character Number' and 'Maximum Character Number' could be added, so as to choose whether to create a code with a predetermined number of characters or within a range.

I think I did something welcome.

Thanks for the excellent work!

The problem is that the Configuration menu is misleading and it seems that there are no sub menus except by clicking on the individual items.

Solved!
