 - **2026-10-13** · Gradients between process colours blend as inks, as InDesign shows them: magenta to cyan passes through C 50 M 50 (a light lilac) on screen instead of the darker RGB mix, and a midpoint between CMYK or grey stops no longer turns the PDF shading RGB. No readiness percentage change.
 - **2026-10-14** · The Swatches panel has InDesign's header: a Fill/Stroke proxy, Formatting Affects Container/Text and the Tint of the colour in front (a tint alone keeps each object's own swatch). Clicking a swatch applies it to the fill or stroke in front (of the text, when formatting affects text), and the bottom row has New Color Group, New Swatch and Delete Swatch. No readiness percentage change.
+- **2026-10-14** · The Page tool works as InDesign's: a click selects a page and shows its handles and liquid page rule; dragging a handle previews the rule and springs back, Alt-drag resizes the page from the opposite edge, Shift keeps proportions, with a W/H readout.
