When sharing, or changing sharing options, I find the mandatory pop-up review intrusive to the process of sharing content. I welcome the visual reference in an item's page that gives the ability to check, just find the pop-up to be over-bearing and something that you can't switch off as a default.
I don't know what others think, but can we just have either the option to switch off by default sharing review, or have it solely as the visual reminder in the item page - it provides a more than adequate reminder?
