ERPNext has a lot of functionalities to suit multiple use-cases. However, some instances may only require certain aspects of ERPNext. For example, a new shop might be interested only in the stock and selling functionality.
Is there a way to remove / hide features that may not be relevant to certain use-cases? In the above example, hiding manufacturing-related functionalities will make it easier for an end-user.
You want to hide the workspace from users, correct? Or is your requirement something else? Could you please explain further, and if possible, provide a screenshot?
