Very Useful addon, but has the following bug for the trading shortcuts on trading screens "https://screenshots.firefox.com/TTQe9mmReJGQEXEr/artemis.pardus.at" it displays the value NaN, also it will be very helpful if the trade shortcut buttons were customizable similar to the old and now incompatible(with FF> 56 ) Pardus Co-pilot addon

Seriously, this addon is pretty much 100% needed if you're a trader and need to upkeep a player economy... makes life that much easier.
