Yeah sort of. I have a “to-read” folder of anything I’ve been meaning to read (believe it or not, it constantly grows and rarely shrinks…) and I use my top-level bookmarks bar for stuff to look at, usually cool FOSS projects I stumble across and want to try out. I don’t use it the exact way you talk about though, eg I usually don’t edit the bookmark name but the webpage title is usually descriptive enough for me.
I guess you could keep your phone in a faraday bag and take it out when you need to make a payment. But then you’d be liable to be charged any time you have your phone out, unless you go out of your way to remove the card from the case, which defeats the point.
