I completely agree and wrote about it too (https://leenewell.medium.com/where-did-that-quote-go-2c548558ff9b) I also had Day One for several years before I realised how useful it could be.

One of the things I like best is that if you share a webpage to Day One using the Safari share button, it saves the link AND creates a PDF of the complete page which you can then view offline. Add your tags and it's such a great scrapbooking tool. I use this feature as a 'read later' tool too - just take with 'read'.
