Guides: a Cmd/Ctrl+Shift double-click releases the guide under the pointer

A double-click on a ruler guide with the Selection, Direct Selection or
Group Selection tool did nothing, whatever keys were held. A guide could
be released only with View › Guides › Release Guides.

With the Selection, Direct Selection or Group Selection tool, a
double-click with Cmd/Ctrl and Shift held now runs view.guides.release
on the ruler guide under the pointer (index) or, when no ruler guide
is there, on the guide path under it (ids). Nothing is released while
guides are hidden or locked, and a double-click without both keys does
what it did before.

 - **Ruler guides as layer objects:** a guide goes on the current layer, shows, hides, locks and is deleted with it, is listed in the Layers panel (its row selects it) and moves to another layer (`guide.setLayer`, or its row dragged onto that layer's rows); guides on a hidden or locked layer can't be selected, moved or deleted, Duplicate copies a layer's guides and Merge Selected and Flatten Artwork keep them on the merged layer; guides from files saved before guides had layers go on the top visible, unlocked layer when the document opens. Not done: guides stacked among the art of their layer (they are listed above it), a guide row's own eye and lock. Lock Guides also locks the objects made into guides: they can't be selected, moved or deleted (#1543); they are drawn in the guide colour and style of Preferences, and a dragged selection snaps to ruler guides with Smart Guides on (#1583, fixes #1534). The Transform panel shows a selected ruler guide's X or Y, and typing a value moves it (#1659, part of #1597). This is not established by the documentation we could find: the public help pages on guides, rulers and the Transform, Control and Properties panels (read again on 2026-10-14) describe selecting and dragging unlocked guides and the panels' X and Y for a selection, not a guide's position in a panel, and the one public statement of it is a user's [community answer](https://community.adobe.com/questions-652/adding-a-new-custom-guide-785586), which is not documentation. It is kept as a convenience pending the owner's decision, with no parity claim and nothing counted towards a score.

 - **Layers panel:** every layer, sublayer, group and object is a clickable row at any depth: a click highlights it and makes its layer current (new art goes there), Shift-click a range, Ctrl/Cmd-click toggles. Sublayers are no longer treated as objects: clicks, marquees, Select All and the Select menu take the art inside them, and each sublayer selects in its own colour. Selection squares on rows with selected art (click selects a row's art, Shift adds or removes; dragging the square moves the selection to another row, Alt copies), the eye and lock on every row with drag-down-the-column (one undo step), Ctrl/Cmd-click an eye for per-layer Outline, Alt-click an eye or lock to hide or lock the other layers (again: show or unlock them all), triangles with Alt to open or close everything inside, drag and drop rows above, below or into layers and groups with a drop line (Alt copies) and a dimmed copy of the row under the pointer (dropped on the trash rows are deleted, on New Layer duplicated, as in Illustrator), inline rename, Delete key on highlighted rows. Buttons and the full panel menu: New Layer/Sublayer (Alt: options, Ctrl: on top), Duplicate, Delete, Options for Selection, clipping mask, isolation, Locate Object, Merge Selected, Flatten Artwork, Collect in New Layer, Release to Layers (Sequence and Build), Reverse Order, Template, Hide/Outline/Lock Others and Show/Preview/Unlock All, Paste Remembers Layers, Panel Options (row size, thumbnails per kind, Show Layers Only). Layer Options: name, colour (presets, each with a chip of its colour, or custom), Template, Lock, Show, Print, Preview (outline drawing and clicking) and Dim Images to %. Every operation is a command (`layer.move`, `layer.highlight`, `layer.merge`…) with validation against cycles and invalid nesting. A document opens with only its top-level layers open; the rows left open are saved in the native file (nothing is written for the default) and reopen that way. Only the rows scrolled into view are laid out, from a row list made once per change: a layer of 5,000 groups of 10 paths, all open, draws the panel in 0.4 ms a frame instead of about 29 s (#638).
   The Filter button at the right of Search All keeps the rows that are of an object kind ticked under By Object (paths, shapes, text, images, effects, groups, linked files, guides) and in a state ticked under By Layer (locked, hidden), with the rows that hold them; a section with nothing ticked takes every row. The filter combines with the search, the button is lit while a filter is on, and Clear All in its popup turns the filter off (`ui.layersFilter`). The filter lasts the session.
   The panel menu's Save Selection submenu has Save Selection…, Update Selection and Edit Selection…, enabled and run as in the Select menu, and lists the document's saved selections: choosing one selects its objects again (`select.recall`).
