A good feature would be an option to create/add subcategories for shop items, and add plans to buy them.
Let's show you an example. The first image shows player models, and Custom Weapons (each separated by subcategories). The second image shows Plans.
(About subcategories, this is just an example, the main idea is making a way to add them for every single item possible)
Both features (sub-cats and plans) are currently added in Zephyrus Store.

Plans:
