We should consider moving this page outside the "Shop features" section, since it can be used by bar/restaurants.

	Both the customer display and POS display should be at least 6 inches. However, a larger screen
	is recommended for improved end-user readability.
	Both the customer and POS displays must have a minimum diagonal size of 6 inches.
	For optimal readability, larger screens are recommended.

• I would specify "diagonal size" even if it's the common way to measure screens.
• "Larger screen" is quite vague. If possible, it would be helpful to recommend a specific size.

I understand how vague "larger" is, but it really depends on how someone uses their POS, whether on their phone, tablet, or computer; it all works as long as it's at least 6 inches. I would say it's up to them; some people might feel comfortable with a 6-inch screen, while others might find it way too small.

	#. Click the :icon:`fa-ellipsis-v` icon (:guilabel:`vertical ellipsis`) on a POS card.
	#. Click :guilabel:`Customer Display` to open the display remotely.
	#. Click the :icon:`fa-ellipsis-v` (:guilabel:`Dropdown menu`) icon on a POS card.
	#. Click :guilabel:`Customer Display` to open the display remotely.

I think this could be confusing, the toggle here on the pos card says:

So I see dropdown menu mentioned, but there's another icon that's also a vertical elipsis but the toggle doesn't say that

• the hamburger menu inspection also shows dropdown:

For now, I'm switching to "Dropdown menu" as suggested because title = Dropdown menu, but I still think it could be confusing, wdyt?
