The Quick Notes feature with iPadOS 15 not only provides a way to quickly create a note, but it also links notes to apps if they are set up for it. An example, when I open this site in Safari on my iPad the note that contains the link of this site pops up as a thumbnail at the lower right and it goes away when I scroll the page. I am creating scratch note of ideas related to this blog. So far I’ve found that I can also link a note to a list in Things.
