Proposed 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.

@gruber would it save your annotations to the safari page and you’d have to like keep the tabs open? (Don’t make us have as many tabs open as you do😂) or have it like save to files?
@tday891 No of course it shouldn’t require you to keep the tab open. It’d be saved (and synced) like bookmarks.
@gruber @tday891 I agree. For me, I sure pay enough for more iCloud Storage & etc. But it beggars belief how much various small but important data is stored on likely hundreds of millions of free iCloud accounts.
