sort of like a more accessible bookmark, separated out so as to not get buried within 800 tabs (if you're anything like my mum). it's not anything groundbreaking in actual use, I guess it kind of just appifies a given webpage (there is some technical nuance that I'm kind of glossing over to assure standards compliance and help them perform better offline).

It can be kind of nice on a phone to eliminate some of the UI chrome given the limited screen real estate you have.
