Would it be possible to add a variable number of prongs?
For example in the image below, when you select the “six prong setting” in the “Main Gems Prongs” menu, you could instead have an input field where you could choose different integer values, (eg. 5, 6, 7, etc.), and another field where you can add an offset angle?
This addition would make the tool much more flexible in terms of design options.
