I'd like to have the option if all conditions should be true for my smart product list, or if either condition can be true. If I want to create a product list where field A contains either X, Y or Z I have to create multiple lists or use TextOption instead.
This suggestion comes from a partner.
Why not go all-in and create a full-blown expression editor where you can roll your own boolean expressions, like:
Name IS EMPTY OR Category CONTAINS "Swimwear"
AND
Stock Balance > 0
AND
Color IS "Blue" OR Color IS "Red"
