The selection of values within the dropdown menus in Shopware Admin is very error-prone.

For example, if additional countries are to be added or removed within the sales channel, the menu only ever shows 25 entries and each entry has to be clicked individually. This is very error-prone and you should also be able to select/deselect “all” entries.

This would make it easier for large customers to use the Admin, as the problem occurs at various points in the Admin.
