Separate categories and landing pages for editing and assigning
Something that is not clear to us is that a category right has an influence on the landing pages and that those who are responsible for the landing pages can also make category changes.
We therefore have the following suggestion:
From the fact that both landing pages and categories can be found under the same ‘Categories’ menu item, it makes sense that both areas may also have overlapping rights. However, it makes little sense to us that editing categories and adding layouts to a landing page are controlled via the ‘Edit categories’ permission.
From our use case, we can therefore only suggest that landing pages and categories be better separated from each other.
It would be nice if both areas could be managed separately with their own rights.
I would also find it much clearer if the landing pages had their own menu item in addition to the categories with separate rights.
For us, the two areas have little in common in terms of handling, except that from a technical perspective they are both elements that a customer can navigate to in the shop. However, this grouping would already be given by the superordinate menu item ‘Catalogues’.
In terms of maintenance and care, the areas are completely different for us, so that the common page of the two topics does not contribute to the clarity and separation of the areas.
While the categories are part of the products and thus the maintenance of the product data, the landing pages and their design are part of the marketing area. In our view, the two otherwise separate areas are currently combined on the categories page for no recognisable reason.

TL;DR:
In short this is about separating Landingpages and Product Categories.Currently they are two different topics on the same page.
They have overlapping user-permissions which do not fit the use case of different Teams managing those different topics.
