Ability to add new sorting columns in shopping
It would be incredibly useful to be able to add your own sources to sort. Like being able to sort by avg daily sold, vendor sell or your own custom price source.

It would also be great to be able to search for a range of sale rate. For example filter any items of your search with less than 0.3 sale rate.
I'd be a big fan of this. For example for Vendor searching, being able to sort by "Difference between vendor and buyout" (In raw numbers, not a percentage, as that's often misleading)
