The label management is scattered in the system and it becomes a time consuming operation especially for retail operations. For buttons of the POS interface we need to create different layouts for each language; for some other parts of the user interface we can use the "Labels" form under Retail module. For custom warnings we are using the usual D365 label management, for right click options we have another ground.

The idea is having a single framework to manage all the user interface labels and enabling the users to change all the labels in one place (Labels form might be a good choice).
