If a user is editing a product and there are many layers (3 or more) it can be hard to know which is which. It would improve UX if the selected/active layer would get another colour so that the user is aware easily of which layer is active.
Simple tweek that would make this plugin easier to user which means happier customers and more money on the bank :)
You can set the color in the UI & Layout Composer of the current selected layer.
