This mod updates option price after option change.
E.g. you basic price is 35, you choose option with price change -15, then your price near choosed option will change to 20.

Tested on OC versions: 2.0.X, 2.1.X.

If you want to change currency sign, just simply swap from xml file: "zł" to e.g. "$".

I'm not a developer so in case of any support my skills are limited.
