Going back to a save left the last run's picture on the output node, so the canvas and the picture told different stories.
- api/workflow_saves.py keeps what each output node made, previews too, the newest 16, and read_group gives them as `outputs`.
- ui_snapshot_bar.js puts them on the nodes through the tab's changeTracker (store, restore): no `executed` event, so no plugin takes them for a new run. Several runs sit on the node as a batch does. A node the save has no picture for goes empty; Load Image's own picture stays (snapshot_plan.outputsAt).
The lit number went out every other time with a Preview Image on the canvas, and an empty undo step came with it: a loaded workflow serializes a little differently from its file, and a node gains an empty widget list when it shows a picture. The number now goes out only when the canvas really changed (withoutEmptyValues), and those differences take no step.

A walk through the whole flow, as a user would, showed what felt wrong.
The folded bar floated over the canvas: it is now a handle on the canvas's
bottom edge. The bar lives in the canvas's panel, so the logs stay uncovered
and it wraps before going under ComfyUI's canvas tools; it holds the newest
six saves, the rest behind a button to the Saves page, instead of growing
into a block. A lit number now means the canvas stands at that save, going
dark on any change or undo. Words float over the bar and leave with the runs,
and on the page a kept card is a toast and runs show on their own save, so no
button moves under the pointer. Removing a save tells the next one what it
changes now, and the Saves view says the way back to the cards.

Presets, combos and Add to saves took more to keep sensible than they gave,
so a save now only becomes a new workflow card and only the canvas makes one.
The panel above the bar moves to the Saves page, a part for each canvas, open
or not, with each save's pictures and its runs: the whole group in order, or
one save alone. Running moves to snapshot_run.js for the bar and the page;
what is clicked goes in in click order, and closed canvases run too.
A run taken off ComfyUI's queue is now forgotten at once, so "runs to go" does
not stay wrong for a day. A first save on an unsaved tab now reaches ComfyUI's
draft of it, so a reload right after keeps the tab's saves on it.

A save copies to a workflow card, a preset of a card with the same structure, or a
combo; a card's preset can join the open canvas's saves. The Workflows page lists
every group, so saves of a closed tab or a deleted file can be opened again, on a
new tab where the group goes on, or removed. A card keeps no key of a canvas's saves.

Saves move from the page to a store (api/workflow_saves.py), a group for each
canvas, found by a key in the workflow's extra or by its file, and go into
backups. The bar follows the open tab. A save's runs are named to the server, which
finds their pictures in ComfyUI's history, so a reload during a run loses nothing.
A save opens above the bar with what it made and what changed; removing one goes to
the Recycle Bin, and a group past its most takes no more and drops nothing.
