SFM-Factory-Studio

Stability

• Fixed game freeze when opening the editor
• Fixed crash when dragging a block into its own condition body
• Fixed blocks sometimes not appearing until another click
• Multiple performance optimizations: smoother editing on large programs, no more high-frequency disk writes

Slot number learning

• Open a machine's screen and its slot numbering is learned automatically — no manual storing/fetching
• When slots are not exposed in the machine's side config, the picker now explains why and how to fix it

Dragging & editing

• Dragging rework: pressing no longer reorders instantly, quick clicks no longer shuffle blocks, subtler drop hints
• Fixed left-click opening a menu instead of dragging blocks
• Box-select blocks and batch-edit: unify labels / sides / counts, swap input ⇄ output
• Multi-select resources; multiple resources join automatically with "and"
• Card copies (＋) stack neatly; the footer − removes the bottom copy
• Row context menu: copy / labels / paste / delete / move up / move down / insert below

Natural phrasing

• Blocks read like sentences: "When take 64 [iron ingot] in total from [warehouse]:"
• The side chip always shows "default side" instead of hiding in the extension menu
• Condition editor trimmed to match official examples; rare options moved into "More…"
• Card search redesigned: press / for a real input box, pinyin search (ronglu → 熔炉), Enter to jump

Also

• New onboarding help page (first launch only) and 4 one-click example factories
• Toolbar folds on narrow windows; popups stay inside the canvas
• Fixed official templates pasting only a comment, leftover Chinese in the English UI, expand button overlapping ✕, and more
• NBT picker drops the empty "All items" tab
• The 1.20.1 build now ships the same server-side TPS protection as 1.21.1 (off by default, configurable)
• Author website added to the in-game mod description
