In trade gecko, when you click into the price field you get a list of pricelist prices shown in a dropdown that you can pick from for the product.
I think this would be a cool feature to implement ourselves, especially for Trade Gecko as it would give a more consistent feel to customers when comparing our system to Trade Gecko.
It allows customers to more easily switch pricelists when on a quote. I don't know how often this is done, do customers almost always just use the default list for their customer? It seems like switching between lists must be a use-case though if Trade Gecko has implemented this feature themselves, especially for customers that don't have a default pricelist set.
