PVU Profit & Price Tool

A great tool for Plants vs Undead that will allow you to:
1) Whenever you're in the marketplace, it will display the conversion automatically when it comes to PVU per month of each of the plants so you don't need to calculate yourself.
2) Through the extension icon, you can also two-way convert PVU to LE, LE to PVU and BNB to PVU at current market prices.
3) You can also set the exchange prices for PVU->LE and LE->PVU completely custom and applies right away on marketplace.
