When configuring a product feed for browse abandonment I would love to see the option to select the last viewed product categories or tags of the last X days.
This option would be great to be added to the (What products should the customers view first?) as well on the (If the customer has limited history, what should they view instead?) option.
Reason for this is that you might look for a certain product but there might be several more similar products in a particular product line segmented by category or tag.
Happy to hear your thoughts on this one.
