• Visual node editor v1.1 "quick wins". A tab may now be left empty (delete the effect node; a + Add effect placeholder retypes it); undo/redo is snapshot-based (one drag or one action = one step, up to 100) and recompiles the whole effect; a broad set of keyboard shortcuts was added (Del, Ctrl+C/V/D/A, Ctrl+Z, Space, R, K, F/Home, Ctrl+S, Tab, Ctrl+G, [/], ?); the timeline gained a tick ruler, keyframe clamping to [0, duration] on drag with an out-of-schema-range red highlight, and a draggable duration bar; numeric fields edit inline (select-on-focus) with no floating popup, and wired slots/params render read-only with a source badge and a "go to node" affordance; the bind value node shows a binding dropdown and labels its output by the binding's unit. COLLECTION is no longer offered by the schema the editor palette is built from. Editor-only: no datapack field, UBO, API or wire change, PROTOCOL_VERSION unchanged. Documented in the guide. Not verified in game.
• Visual node editor: build, live-play and export effects in a local web UI. /vfxeditor starts (and a second call stops) a loopback HTTP/SSE bridge that serves a vendored LiteGraph editor from the jar and drives the running client: a schema-driven palette, one tab per effect, an inspector (constant / start-end / keyframes / binding / expr), a timeline with draggable keys and play/stop/loop transport, and live incremental edits gated by a monotonic revision. It exports a real datapack to a world datapacks folder, a loose folder or a zip (per-Minecraft-line pack.mcmeta, plus a sidecar holding the graph layout), imports a folder or zip back, reconnects the event stream with exponential backoff (1 s/2 s/4 s…) and re-sends the full effect when the revision diverges, and undoes by restoring the model snapshot then recompiling the whole effect (never an incremental game undo). Client-only, no new dependency, no datapack field, UBO, API or wire change, PROTOCOL_VERSION unchanged. Documented in the guide. Not verified in game.
• Authored preview mode in the visual editor. The transport switches Exact/Authored: Authored plays the collection root with authored timings, so fades, loops and durations read as they will in game. Editor-only: no datapack field, UBO, API or wire change, PROTOCOL_VERSION unchanged. Documented in the guide.
• Reference nodes and nested collections. A tab can instance another tab (cycle-guarded, nesting depth capped at 4); Exact preview recursively expands nested collections with accumulating delays. Editor-only, no wire change. Documented in the guide.
• Scrub is pause; export v2; editor QoL. Scrubbing the playhead pauses instead of auto-resuming; export carries vfx_curves/vfx_particles blocks verbatim, writes multi-namespace packs in one pass, and migrates the sidecar to v2; socket groups start collapsed, effect nodes gained a canvas solo badge, and Ctrl+G groups persist as named frames. Editor-only, no wire change. Documented in the guide.
