Yes those are definitely not the hardest problems in this space. I was only referring to UX-related features in my original post (i.e. rather than the much more tricky privacy and security related ones), ones that I couldn&#x27;t figure out how to actually <i>implement</i> in the context of a client-side web app. <i>Impossible</i> was probably too strong of a word to express that.<p>Thank you for all the interesting ideas and resources though! They&#x27;ll definitely come in handy when I eventually revisit this space when I have more time later on.
