Few Basic Questions | WordPress.org

Hi, a few questions please –

1. Does the plugin work with the Flatsome template? Because I set everything according to the guide line and I don’t see any new part on the product page.
2. Is it possible to define only one feature – like color?
3. Is it possible to define that a product that is not in stock will not appear at all?
4. Is it possible to control the size of the displayed images? (Desktop and Mobile)

Thank you,
Oren
