If it were possible it would be great if it could integrate with Facebook Marketplace, as this is one of the largest and fastest growing sales channels.

This is great..

please make sure to include google shopping ads

Yes, multiple sales channels would be great ... especially a product feed for Google Shopping Ads

This feature would be great!

Absolutely, but please do it better. There are some major issues with the way Shopify does it.

For eBay you need to have ability to chose the location the product is being shipped from. The Shopify integration automatically uses the owners location as the place where the inventory is physically located. eBay deactivates listings when they verify shipping and the tracking originates in China or a different US location then the owner lives. I had to delete the integration so eBay would not shut me down.

For Amazon, I only list about 300 of my 5000+ Shopify products. Linking products must be done by hand one by one with no search function available. It means scrolling through a massive number of items (only 4 displayed per page) to create the link. When I find one listing and set it up, the system then brings me back to the beginning where I have to start over. Very frustrating! Hopefully these make sense, if not, I'd be happy to show someone. :-)

And maybe Etsy ;-)

This feature would be smacking and is very desireable.
