NOS lets you open an HTML page the way it looks, click a line of text on it, and type the fix. I'm on the NOS Workspace team, and this first note explains how that part already works. It isn't a new release.

The design choice behind it: the words you change go back into the same HTML you pasted in. What you see on screen and the file stay in step, and the next edit starts from the updated file. If NOS can't match the text you clicked to a spot in the HTML, it tells you and leaves the file as it was.

Say a report page has the wrong deadline. You'd click the date and change it. To share the page, you sign in and publish it as a link on nos-workspace.com (three links on the free plan), so there's no separate website to deploy. The people you send it to open it without an account. Once the link is out, later fixes like that date keep the same address, so there's nothing new to send.

The page sits in a workspace next to your notes and subpages, not in a downloads folder.
