John GruberProposed feature for Safari: Markup.
Highlights and notes, with Pencil support, as an overlay atop the original page. Personal, not public, but synced via iCloud. I’d use this every day.
Eric J@Eric_Neue I recall seeing and playing with some attempts at this. But I think it has to be built into the browser to work well. And I definitely want highlights, not just sticky notes. (But sticky notes are essential too.)
