A section stayed on with nothing in the browser to switch it off; only the viewport's context menu had Remove Section. While there is one, the browser now has an Analysis folder listing it. Its eye (and the folder's) hides the section and shows it again on the same plane; a double-click or Edit Section Analysis opens the dialog, and Delete removes it. Browser rows with an eye publish an `eye:<label>` handle for automation. Fixes #822 Co-authored-by: Claude Opus 5.5 <[email protected]>
