- PDF/X-4 export (`file.exportPdf {standard: "x4"}`): an output intent with our own Generic CMYK ICC profile (lut16 tables generated from the parametric press model), GTS_PDFXVersion in Info and XMP, `pdf:Trapped` in XMP as in Info, RGB images without a profile tagged sRGB, no image interpolation (none in PDF/A either), and built-in PDF/X-4 checks reported as warnings. qpdf finds no errors in the result.
- EPS place: placed at its (high-resolution) bounding box and shown, printed and exported through its TIFF preview, or a placeholder when it has none. PostScript itself isn't interpreted.
- Preferences: Dictionary (user dictionary; `spelling.setWords/words`), Spelling (Dynamic Spelling: red squiggles on the canvas, also Edit ▸ Spelling), Autocorrect (word list, applied as you type), Notes, Track Changes, Story Editor Display and File Handling (recovery interval) sections.
- Colour management exposed: Edit ▸ Color Settings (`color.settings`: RGB/CMYK working spaces, intent, black-point compensation; `color.loadProfile` for ICC files; `color.convert` through the working spaces, with gamut checks) and View ▸ Proof Setup / Proof Colors (press, sRGB, legacy Mac RGB, colour-blindness simulations, simulate paper) on the canvas.
- Colour management exposed: Edit ▸ Color Settings (`color.settings`: RGB/CMYK working spaces, intent, black-point compensation; `color.loadProfile` for ICC files; `color.convert` through the working spaces, with gamut checks) and View ▸ Proof Setup / Proof Colors (press, sRGB, legacy Mac RGB, colour-blindness simulations, simulate paper) on the canvas. Placed images are shown through their embedded ICC profiles, and CMYK images through their own profile or the working CMYK space, with the settings' intent and black-point compensation.
- Keyboard: Tab / Shift+Tab hide and show all panels / all but Tools (`window.hidePanels`, `window.hidePanelsExceptTools`); Cmd+F6 / Cmd+Shift+F6 cycle documents; panel fields are reached with Tab and Escape returns to the layout.
- Smart guides and snapping (View ▸ Snap to Guides / Snap to Document Grid / Smart Guides, `view.snapPreferences` and Preferences ▸ Guides & Pasteboard): moving, drawing, resizing, rotating and pen/anchor drags snap in order to the document grid, ruler guides (a page's own and its parent page's), margins and columns, other objects' edges and centres (parent-page items too, by visible stroked bounds), equal spacing (centred between two neighbours too), matching dimensions, the baseline grid and matching rotation, with guides, gap marks and measurements drawn on the canvas. Shift and Cmd constrain the gesture.
- View ▸ Rotate Spread (`view.rotateSpread`, `layout.rotateSpreadView`): the spread in view turns in quarter turns on screen (stored with the document and in IDML's spread transform; output is unaffected). The canvas maps each spread through its own transform, so tools, snapping, resize handles, guides, overlays and rendering all follow the turned spread.
