Product Visibility & Default View

[spidawebs]

I have a few issues I can't resolve:

1) When a product is out of stock I would like it to disappear off the website so the visibility needs to be "nowhere". Then when it comes back into stock I would like the visibility to automatically go back to "everywhere". At the moment I have to do all this manually. Is there a way of doing it automatically?

2) On the category page on the website, the products are defaulted to show as a list. I would like them to show as grid. How do I do this?

I know this is old thread, in case someone still searching this solution 1. see my post here https://forum.thirtybees.com/post/14835 (but I have performance issue with this method so I use this module https://addons.prestashop.com/en/stock-supplier-management/19051-enable-disable-product-when-stock-changes.html) 2. I think this is bug https://github.com/thirtybees/community-theme-default/issues/56
