Love the theme, please help me perfect the setup :)

Making a new site after a long (years!) break.
Wow, what a great theme this is. So complete!

Anyway there was a few things I couldn’t figure out and was wondering if I could get help.

1) To make an “all stores” page. https://cp1.wlthemes.com/all-stores/
Is there a [short code] for that, or how is it done? I started manually but can already see it will be a pain to keep up to date.

2) For a store with no coupons there is a message “There were no results found for your search query.” https://cp1.wlthemes.com/store/bathempire/
Where can I edit this one?
(I was thinking to add “you may like instead” and pull in some kind of featured stores?)

Many Thanks for reading!
