Ran v4 side by side to see what the difference actually was, and it was not spacing. v4 fills the window edge to edge and divides its zones with hairlines; v5 floated rounded, shadowed cards on a visible page background. One reads as an editing suite, the other as a dashboard. So panel gains a second variant. "default" is still a card, for something that floats -- inside a window, on a page. "zone" is a region of the app: square, no shadow, no border of its own, divided from its neighbours by the one hairline everything else uses. The workspace keeps no gutter between regions; the preview zone is flush, because padding around a picture is a frame nobody asked for, and its surround is letterbox black rather than a panel colour. The right column was two stacked panels with two heads for one thing. It is one zone now. And the surfaces have depth, derived from each theme's own elevation scale so neither needs a rule of its own: a vertical fall on every band and every raised control, the accent gradient and a bloom under a primary button, a wash off the top-right of the page, tokenised thin scrollbars, an accent mark on every zone title, and v4's film grain -- overlay at 3.5% on dark, multiply at 1.5% on light, and painted with no z-index so anything that opens above the frame stays crisp.
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.
