New: Four workflow execution modes — Static (always use one selected workflow), Random (pick randomly from checked workflows on each run), Sequential (cycle through checked workflows in order, looping — each click advances to the next), All (send all checked workflows to ComfyUI in a single click)
New: Named workflow pairs — save a suffix + workflow JSON under a custom name, load it by clicking, delete with ✕ button. The Default entry is always present, protected, and reflects your current saved settings
New: Import / Export workflows — export all saved workflows to a .json file, import them back on any machine. Located in the settings header for quick access
New: Active workflow row highlighted with a purple left border when selected
Fix: Sequential mode now correctly advances the index on each click (index was missing from the storage read call, causing it to always send the first workflow)
Fix: All and Sequential modes were silently falling back to Static due to a mode validation bug in the content script

New: Workflow management — save named suffix + workflow JSON pairs, load them by clicking, delete unwanted ones. The list always contains a protected Default entry that mirrors the current saved settings
New: Workflow mode — Static (always use a selected workflow, defaults to Default) or Random (pick from checked workflows on each run)
New: Model selection — Default, Random (pick from a selection), or Static (always use a specific model), loaded from your ComfyUI server
New: Seed control — Default (use workflow seed) or Random (new seed on each run)
New: Active workflow row highlighted with purple left border when selected
New: Version number displayed in settings page header
New: Reset defaults button restores server URL and workflow without touching saved pairs
Fix: Positive/negative prompt detection now traces the node graph — injection only targets positive CLIPTextEncode nodes regardless of workflow complexity
Fix: innerHTML replaced with safe DOM API calls throughout settings page
Fix: Default values pre-filled on first install and restored automatically if storage is empty

Fix: CivitAI prompt was no longer being injected — caused by the graph traversal recursively marking positive CLIPTextEncode nodes as negative. Recursion is now scoped to known conditioning passthrough nodes only (ControlNetApplyAdvanced, ConditioningCombine, etc.)
Fix: innerHTML replaced with safe DOM API calls in options page to pass AMO security linting
New: Seed control — Default (use seed from workflow) or Random (generate a new seed on each run). Defaults to Default.
New: Model list grouped by directory with folder headers, making it easier to find models in large collections
New: Error responses from ComfyUI are parsed and displayed meaningfully — missing model name shown instead of raw HTTP status code
New: Failed requests show a red ✕ on the button (mirroring the teal ✓ on success), resets after 3 seconds
New: Default values pre-filled on first install — http://localhost:8188, standard SD1.5 workflow, model mode set to Default

New: Model selection mode in settings — choose between Default (uses checkpoint from workflow, name displayed automatically), Random (pick from a curated list, one chosen at random on each run), or Static (always use a specific model). Models are loaded directly from your ComfyUI server and grouped by directory.
New: Seed control in settings — Random generates a fresh seed on every send, Workflow preserves the seed defined in your workflow.
New: Default values pre-filled on first install — server URL (http://localhost:8188), a standard SD1.5 txt2img workflow, and model/seed modes set to sensible defaults.
New: Error feedback — failed requests now show a red ✕ on the button (with --mantine-color-red-light background) mirroring the teal checkmark on success, and error messages are parsed from ComfyUI's JSON response to show meaningful info (e.g. missing model name instead of a raw 400 code).
Fix: Positive/negative prompt detection now traces the node graph instead of relying on keyword matching — the negative input of every sampler node is followed upstream to correctly identify all negative conditioning nodes regardless of workflow complexity.
Fix: Button no longer appears next to "Negative prompt" copy icons on ComfyUI-generated image popovers.
Fix: Button injection restored on /images feed popovers that use a simpler DOM layout without a button group wrapper.
