Requesting support for the "GUIShop - Recovery rate (Sell/Buy)" config property

Hi! I am loving this mod so far and especially the support for Item Cost Calculator it brings. The ability to sell lots of goods for less than one currency unit per sale unit is fantastic. Thank you for making this!

I have one piece of feedback I'd like to share and additionally a feature request.

Feedback
At first I was not able to figure out how to use Item Cost Calculator with Shop. I had flip through the Support forum to find my answer. It would be lovely if the product page could document "shop.fill.icc` and the UI Calculate button (as well as its dependency on ICC) so people don't have to hunt for that info and fall back on investigative work to connect the dots.

Feature Request
Item Cost Calculator has a config field called "GUIShop - Recovery rate (Sell / Buy)" which, for GUIShop output, lets ICC calculate Sell costs as a fraction of Buy costs. This is a lovely lovely feature and I would love if I could use this with Shop on my server.

Thank you! I appreciate what you do for this community!
