Release notes

The 1.0 of Pixel Perfect Advanced: a complete design-overlay workflow for pixel-accurate frontend work, free and fully local. Everything below is included, with no tiers and no upsell.

Feature-complete release candidate: the layer cap is gone and the last rough edges are sanded down ahead of 1.0.

• Removed the layer cap - add as many overlays as you need
• In-panel help and a feedback link, plus the contact form on the site
• Faster rendering with many layers on large, scrolling pages
• Fixes across positioning, per-site restore and panel focus

Cross-browser beta: the extension now builds for Edge and Firefox alongside Chrome.

• Edge and Firefox builds join Chrome
• Firefox sidebar and Chromium side panel reach parity
• Consistent keyboard shortcuts across browsers
• Graceful fallback where a browser lacks viewport emulation

Viewport emulation lands, so you can match a mockup's width without touching your window.

• Window-to-layer viewport emulation to match a design width
• Counter-scaled panel stays clickable while the page is emulated
• System theme option alongside light and dark
• Live viewport width readout in the panel header

Presets and a fifth blend mode: save your defaults and invert an overlay in one click.

• Invert blend mode - five blend modes in total
• Reusable presets for opacity and blend defaults
• Quick-apply presets from the panel
• Remembered default opacity and blend for new layers

The floating panel arrives: a draggable, collapsible panel you can place anywhere on the page.

• Draggable floating panel that collapses to a compact pill
• Switch freely between the docked side panel and the floating panel
• Panel position and collapsed state remembered per session
• Drop an image anywhere on the page to add it as a layer

A real media library: every image you import is kept, organized and one click away.

• Built-in media library for all imported images
• Folders and pinning to organize references
• Reuse any stored image as a new layer
• Thumbnails with quick search

More ways in, and a safety net: URL, paste and drag-and-drop imports, plus undo and redo.

• Add images by URL and by paste (Ctrl/Cmd+V)
• Drag-and-drop images onto the panel
• Undo and redo for layer changes (Ctrl/Cmd+Z / Shift+Z)
• More robust URL import with clearer errors

Precision controls for getting an overlay exactly where it belongs.

• Pixel-precise X/Y positioning and per-layer scale
• Keyboard nudging with configurable small and large steps
• Fit-to-width, center and snap-to-edge helpers
• Numeric fields with drag-to-scrub

The first internal build: overlay layers, core blend modes and per-site persistence.

• Overlay layers with adjustable opacity
• Blend modes: normal, difference, multiply and overlay
• Click-through on locked overlays so the page stays usable
• Fixed and absolute positioning for long, scrolling pages
• Per-site persistence: layers and settings restored automatically
• Side panel controls
• Dark mode
• English and Russian
