Custom item shop with categories. Advanced crafting system addon.

I want to have a custom shop in my game which sells crafting recipes for my crafting system. I know I can use any old shop script, but the list of recipes I have is pretty huge and I'd rather have one specific vendor which sells them nice and categorized. I believe a lot of people use This Script so it wouldn't only be beneficial to me.

I'll use some of the crafting window screenshots to further go into detail.





See how the categories drop down once you use your action key on them? I want something like that, except instead of having things which can be crafted, they will be replaced with the recipes. The window on the right would display the cost of the recipe. Once purchased, the item vanishes from the shop and you automatically learn how to craft the item. Most of this will probably require an edit section in the script. I know this is a huge request, but I'm sure a lot of people would appreciate an addon like this for such a popular script.

Anyway, if you need any more questions just let me know. Thank you.

Here is the link to the original crafting script.
