• Measure (⌘⌥M). A transparent overlay you can drag measurement lines across — length shown live in points, hover the line or its pill to flip to pixels. Drag the caps to adjust, drag the line to reposition, arrow keys nudge, Delete removes. Click once in a flat-colour region and Measure drops an auto-fit cross that snaps to the full width and height of that band — handy for sizing a button, a sidebar, a padding gap. Confirm locks the overlay click-through so the measurements stay on screen while you keep working. • Guides (⌘⌥G). Drop horizontal and vertical alignment lines anywhere on screen. A small HUD chip offers +H / +V / Clear / Lock / dismiss. New guides flash in with a laser-line glow. Drag to reposition, click to select, Delete to remove, arrow keys nudge one point (Shift = ten). Lock flips the overlay to click-through so lines stay visible while every click goes to the app underneath. Guides persist across launches. • Drop guides from the loupe. While the loupe is up, press G to lay a horizontal + vertical guide pair right at the reticle — pinpoint a pixel at magnification, then mark it in one keystroke. • Pixel-walk the loupe. Arrow keys advance the loupe's reticle one source pixel at a time, independent of the system cursor. The reticle eases back to centre the moment you move the mouse. + / − work as zoom alongside ‹ ›. • Bigger loupe. Three more 2-key size steps past the previous cap — useful on a 5K panel or when you're reading pixels from across the desk. • Permission flow that respects your time. The Screen Recording explainer is now what greets you on launch (and any time you tap a feature without the permission yet), so you know why CrossHair needs it before macOS's system prompt ever appears. • 10 languages. English, German, Spanish, French, Italian, Japanese, Korean, Brazilian Portuguese, Russian, and Simplified Chinese. Onboarding, status menu, and Preferences follow your system language automatically. IMPROVED • Preferences modernized. Rebuilt as a single grouped form to match macOS Settings — sectioned cards, SF Symbol glyphs on each shortcut row, secondary reset chips, compact pop-up for the menu-bar click action. • Loupe pixel grid aligns to real pixels. The optional grid (toggle with P) now draws on actual source-pixel boundaries on Retina displays instead of mid-pixel, so each cell is exactly one screen pixel. • SF Symbols in every menu item.
