This is Ren from Shopify's Social Support team. Thank you for sharing your thoughts on this. As it stands, there is a way to toggle some POS Staff permissions. You can find the details and steps here.
Any one of the following permissions can be toggled on and off:
-Access orders at any location -Change location settings -Change payment settings -Change register shift settings -Customize receipts -Log out of the store -Access apps -Access Customers
At this time, sales viewing and cash drawer opening permissions are not changeable - though what I'd like to do is send this to our development team as a feature request. I agree it would be very beneficial to have a broader spectrum of permissions, especially on POS.
