Hey guys, love your addon. I'm a data scientist and find the value this addon brings extremely useful.
There are two simple features I would suggest including to make the pricing recommendations more meaningful:
Standard Deviation: most data scientists look at the avg price, along with the standard deviation to understand not only whether the current price is good, but how much it can deviate. (e.g. something that is priced at 10g, and has an average price of 15g, and a STD of 50s is WAY more attractive)
some way to notate price momentum or a change in historical avg price. I've noticed some disparity between the noted average price compared to my own spreadsheet's historical average price. I'm fairly confident that this is due to the amount of time data is stored. (for example, something that was 1000g last expansion, but sells for 10g now will still show up with an average price of 250g). A function that would either truncate how much historical data is used in figuring out the avg price, or some way to show price momentum (e.g. something that has been historically a higher price, but is trending down) would be invaluable to this addon
If I can be of any assistance with adding these functionalities, don't hesitate to reach out :)
