Road to filters

[serpico]

Beside #839, a place to list ideas about things some of us would like to see in terms of filters to display/hide products in the front end. @raphodn feel free to change the wording.

Use case : I'd like to be able to display the price per kg for a wide variety of cheeses.
there's cheeses then

• I'd like to filter out some categories like grated cheese, appetizer, cheese spreads, sliced cheeses, etc....
• a filter on the country ( only include products sold in a particular country )
• asc/desc ordering based on price per quantity ( at first glance, rather than price )
• display/hide based on packaging size ( being able to focus the display on big quantity )

Ideally the last price and price per kilo would be displayed in each product card to allow quick comparison by user

In conjunction, add a maintenance page or Hunger Game tweak to allow user to see products with at least 1 price but without
cat, quantity or brand, so they can try to fix them - otherwise, in case of product missing a category, it would defeat the filter purpose. And or cover this case in a daily data quality email - I think they have one of those at OFF.
