Hello Gareth,
Thank you for sharing another wonderful suggestion. This will indeed help the SEO of the site if used correctly, I will relay this suggestion to our dev team so they can further discuss if it can be included in the future updates.

Would be useful to be able to make page structures/hierarchies. So instead of having
garethbevan.com/collection and garethbevan.com/page, you could set it to be garethbevan.com/collection/page
