What’s New • Added Fit Values to Selected Artwork above the Generate action • Automatically calculates suitable anchor size, handle size, outline width and gridline width from the selected artwork dimensions • Added larger, full-width size, width and opacity sliders • Added optional numeric/form-based controls through the native flyout Settings panel • Added configurable original-logo appearance: 5%, 10% or 20% black, or keep actual colors • Added raster, vector, AI and multipage PDF arrangement support • Added balanced masonry, tiles and row-based layout modes • Added fitting, crop-focus, spacing, ordering and editable clipping-mask controls Construction Improvements • Anchor and corner markers now use square shapes • Bézier handle heads remain circular • Anchor markers render above handle lines for cleaner intersections • Construction gridlines are created only from straight or angled segments • Curved and radius segments no longer generate inappropriate gridlines • Gridlines extend across—and when necessary beyond—the containing artboard • Default construction color is #4F7FFF to match Illustrator’s selection appearance • The selected logo defaults to a subtle 10% black presentation after construction • Fill, stroke, Use Fill and Swap Fill/Stroke controls are arranged more efficiently Workflow Changes • Removed automatic live application while moving Construct sliders • Slider changes no longer create repeated anchors, handles or other construction objects • Removed the redundant Generate All action • Construction is now committed through one explicit Generate action • Scale recommendations can be recalculated at any time without generating artwork Fixes • Improved combined Illustrator host-engine initialization • Fixed undefined-host and missing-command failures affecting Logo and Bento operations • Fixed selected grouped artwork not being recognized consistently • Fixed duplicated anchor and handle objects during parameter changes • Fixed construction markers being obscured by handle lines • Fixed curve-derived gridlines appearing across rounded artwork • Improved compatibility with older ExtendScript/CEP JavaScript engines • Improved extension startup and panel-state handling after installation
