Upgrade the List-Collections template for Shopify Warehouse 1.16.4 Theme

We are looking for a Shopify expert to upgrade our List-Collections template for the Warehouse 1.16.4 theme. The ideal candidate should have experience in Liquid programming language.

We use the list-collections template quite a bit on our site. It has a drawback in that it can only create menu tiles for collections (https://support.maestrooo.com/article/86-list-of-collections-creating-custom-page-that-display-collections).

We need to have the list-collections template (or a new, similar template) support both pages and collections so that the resulting page will show both as choices.

For example:
https://www.countrychristmasloft.com/pages/christmas-lighting

Each of these tiles represents a collection. We need it to be able to represent mostly collections, but with a few representing other pages instead.

Skills and experience required:
- Proficiency in Liquid programming language
- Strong understanding of Shopify and its themes
- Experience in improving navigation and user interface
- Knowledge of optimizing page loading speed

If you have the necessary skills and experience, we look forward to receiving your proposals.
