- Publish mixed-filament slots as whole units: serialize the filament_mixed_* definition into project_config on import, grow the receiver's parallel arrays in lockstep, and report unappliable definitions as skipped instead of dropping them silently
- Per-extruder printer selection: one inner tab per extruder, rows keyed by full "#N" ids; single-extruder receivers collapse variants onto their slot (first applied, rest skipped), multi-extruder receivers override element-wise
- New per-slot "Enable" toggle gating what gets published; enabling a mix auto-enables + Full Publishes its components
- Mixed page previews: fixed-size ratio bar, ternary triangle (3 components) and Material Ratio vs Model Height graph (gradients), always visible regardless of Enable
- Tab strip shows full swatch compositions with adjustable spacing; barycentric helpers shared via FilamentBitmapUtils
Per material slot, the Publish dialog can now embed the entire filament preset ("Full Publish") and require a curated filament type and/or colour:
- On export, full-publish vector options are masked to the author's slot so unrelated slot data never leaks into the published file.
- On load, slots are matched by the published type: a match keeps the receiver's material (full dumps ignored, partial keys applied); a mismatch replaces the slot with the first visible same-type library filament, falling back to a temporary embedded preset or skipped keys when none exists. Required colours apply regardless of the type match.
- The receiver's slot count grows only to the highest published slot.
- Published 3MFs load as a new project: the file's path is not adopted as the project filename, published metadata is stripped from the model, and the file is added to recent projects.
- Notifications list replaced slots, and the edited filament preset is refreshed so applied values surface in the GUI.
- Dialog: "Full Publish" toggle replaces the material opt-in and select-all headers; new Color/Type requirement rows with swatches.
- Add Ctrl+Shift+E shortcut for the Publish dialog (menu, key handling, and the keyboard shortcuts dialog).
- Tests for export slot masking, metadata round-trip, replacement semantics, slot growth, and skipped-key reporting.
