+- 2026-10-15: Double-clicking the status bar's preflight count or its light shows the Preflight panel, as in InDesign.
 - **2026-10-14** · The Type tool draws a new text frame over a locked empty frame, as InDesign does, instead of turning the locked frame into a text frame. No readiness percentage change.
 - **2026-10-14** · 100% black shows as pure black on screen by default, as InDesign's Appearance of Black does out of the box (Display All Blacks as Rich Black); Preferences › Appearance of Black › Display All Blacks Accurately still shows it as the dark grey it prints, and a saved choice is kept. No readiness percentage change.
 - **2026-10-14** · Pathfinder keeps the frontmost object, as InDesign does: a photo placed over shapes and intersected with them shows through the shapes (it was dropped, and the shapes kept their black fill); Add, Exclude Overlap and Minus Back take the front object's fill too, Subtract still keeps the back one. No readiness percentage change.
