Two pieces of the "port v4's exact UI onto v5's backend" plan: - core/contract.py: new optional ModuleSpec.category field (closed set: continuity, guidance, conditioning, sampling, post, system), validated in core/schema.py, threaded through core/registry.py's FIELDS and to_manifest(). Presentation grouping, independent of STAGE (execution order) -- a module can be stage="sampling" and category="guidance" at once. Only the 4 existing modules that actually render a settings panel (alg, sharpen, appearance, full_control) got a category assigned; the other 12 have none to categorize (no SETTINGS block) and stay uncategorised, which is valid. - v4's frontend (movie_editor/frontend/*, ~29k lines, 61 files) copied verbatim into app/legacy/. core/routes.py's "/" route now serves legacy/index.html instead of the composer entry point; a <base> tag in that file resolves its own relative script/link tags against /funpack/app/legacy/ regardless of what URL it's served at, so every file moved as a unit with zero per-file path edits. Verified live: all 61 assets load 200 OK, the real v4 onboarding screen renders pixel-for- pixel (it's the actual DOM/CSS, not a reimplementation), and several v4 API calls (/api/media, /api/projects, /api/git/status) already succeed against v5's real backend by coincidence of shared route naming -- the rest 404/405 as expected, since api.js's ~90 functions haven't been rewired to v5's actual routes yet (next piece of this plan). The old composer entry point (app/index.html, app/composer/**) stays in the tree, unreferenced, until a later cleanup pass once nothing imports it.

ComfyUI-FunPack v5 — "Cunning Cranberry"
FunPack v4.0.0 is going to be the latest release of classic FunPack. Next update is another milestone update, or shall I say, a full rework.
Maintenance of current FunPack became a mess — forgetting to add or remove buttons from/to UI, finding functions that don't do anything but still present in the code absolutely randomly, trying to keep the UI neat while it has no strict boundaries on how it should look like, and of course — making it easy for users to understand how FunPack operates and how you can operate it — this is all time, money and token-consuming.
General idea behind the FunPack v5 rework is writing it from scratch, with a new architecture where a feature can't be forgotten, where a wire can't be missed, where one failing module never stops whole process from executing. Loaders and features would tell the UI by themselves what sorts of inputs they need and where to put it — and UI will compose them according to design guidelines it would have. Samplers would become independent from features — if a feature is available and enabled, sampler would call it. If it's not — it gets skipped and doesn't even appear in the UI so it won't confuse you.
Most of this comes from a FunUI backend draft that got shelved after understanding on how much time has to be invested into polishing it. Without a community support and wide usage it would become another dead project only one person in the world needs but no one else.
Come to think of it, FunPack already became something alike, with an exception — this project is more than alive, and while I can, I will support it.
Final goal is to make FunPack an ultimate answer for a novice's question "I don't know how to generate — what do I install and how do I start?" and for a professional's question "I need a UI with all the cutting edge techniques available on day 0 — which one?"
Preparation for the v5 had started.
FunPack v5.0 "Cunning Cranberry" — coming fall 2026.
This branch is a clean start. Classic FunPack lives on main.
