Sidebar config editor

Every ComfyTV stage runs against a workflow chosen in its dropdown. The ComfyTV sidebar tab lets you inspect and edit how stage inputs map to that workflow’s nodes — without touching any files on disk. Changes apply immediately.

The same surface that ships in _preset.json is editable here. The sidebar is meant for end users who want to tweak the shipped defaults.

Opening the editor

1. On the left of the ComfyUI canvas, click the ComfyTV tab in the sidebar.
2. Click any ComfyTV stage on the canvas (Image Stage, Inpaint, Upscale, …). The sidebar shows that stage’s currently-selected workflow.

The header shows the stage’s kind badge and the currently-selected workflow label. If the workflow is being seen for the first time and hasn’t been picked by any stage yet, you’ll see a hint asking you to select it once on a stage first.

If the workflow contains Note / MarkdownNote nodes, their content is collected into a collapsible “Workflow notes” block at the top — that’s how workflow authors leave notes for users.

The “Description” section at the bottom shows the preset’s description field.

The sidebar stays empty when the selected stage has no workflow combo (Crop / Rotate / Mirror transform stages, Load Image / Load Video loader stages). Selecting them shows the empty state.

The widget list

Under the workflow notes you’ll see every editable widget in the workflow, grouped by node — each node is a collapsible card. The node header shows the node title, (node type), #id, and a bound / total count on the right.

Each widget row has three pieces:

• .<widget name> — e.g. .seed, .text, .filename_prefix.
• Value editor — the widget’s native input control (number box / text box / dropdown / toggle). Editing here means “replace the workflow’s factory value with this constant”. When the row is bound to a stage input (the dropdown shows anything other than (use this value)), the value editor is greyed out — at run time the value comes from upstream instead.
• Bind to: — see the next section.

Binding options (the Bind to dropdown)

The dropdown lists the stage’s own inputs. The label you see and what it means:

Label	What runs at execute time
(use this value)	The constant you typed in the Value editor on this row — e.g. a model filename.
Stage prompt	The text typed in the stage’s main prompt box.
Stage negative prompt / Stage seed / Stage batch size / Stage lyrics / Stage scale / Stage duration (s) / Stage generate audio / Stage mask (painter output) / Stage pad left/top/right/bottom / Stage feathering / Stage LLM max output length	The current value of the corresponding stage widget. Which ones appear depends on the stage type.
Stage width / Stage height / Stage video length	Derived from the stage’s resolution + aspect ratio + duration.
Upstream image #N	The N-th image wired into the stage.
Upstream image + painted mask (alpha)	Inpaint / Erase only. The upstream image with the painter mask baked into its alpha channel — bind a LoadImage’s image input to this when your workflow takes the mask from the LoadImage’s MASK output instead of a separate LoadImageMask node.
Upstream video #N / Upstream audio #N / Upstream text #N	Same idea for other upstream types.

For a CheckpointLoader’s ckpt_name, pick (use this value) and type the model filename in the Value editor. For a KSampler’s seed, pick Stage seed — that’s all; the runtime generates a fresh random seed each run.

Saving and validation

Editing a value or changing a binding saves immediately. The wire-validation indicators on every stage on the canvas re-run after each save; you can see if a change affected upstream sockets right away.

A save that fails shows an inline error.

---

Editing the workflow itself

The sidebar only edits bindings. To change the workflow itself (rename a node, add a step, swap a model loader), open workflows/<kind>/<name>.json in ComfyUI’s main canvas, edit visually, and save back over the file. The next time a stage picks this workflow, ComfyTV detects the modification-time change and re-reads it — the new structure is immediately usable, no restart needed. Existing bindings keep working as long as the node IDs they reference still exist.

---

Exporting as a shareable preset

At the bottom of the sidebar there’s an ⇩ Export preset.json button. Click it to download the current bindings + metadata as a JSON file named <workflow-slug>_preset.json.

The file you get is the standard _preset.json format (see custom-workflows.md). Typical flow:

1. Drop a workflow JSON into workflows/<kind>/.
2. Open it on a stage, prep it, and tweak bindings in the sidebar until you’re happy.
3. Click Export preset.json.
4. Save the downloaded file next to the workflow JSON, named <name>_preset.json.
5. Share the pair (<name>.json + <name>_preset.json) with someone else. On their first selection of this workflow on a stage, your defaults are auto-applied.

The button is disabled until the workflow has been picked on a stage at least once.

---

Reset to the shipped preset

Next to Export preset.json at the bottom of the sidebar there’s a ↻ Reset to shipped preset button. Clicking it wipes all bindings + metadata for the current workflow and re-reads the on-disk _preset.json once. Any edits you made are lost.

If the workflow has no _preset.json file, the button errors with no shipped preset for this workflow.
