Q1View v2.5.0

Comparator: a synchronized selection rectangle for side-by-side region inspection. Press S to enter selection mode and drag a rectangle on either image; Comparator draws the same region on both panes so the corresponding area can be compared directly, and the rectangle stays locked to that image region while zooming, panning, or resizing. A width × height readout is shown next to the rectangle, and the selection clears with Esc or a right-click. The selected region's score for the active metric (PSNR/SSIM, computed on the color-space-native planes, or LPIPS on the cropped region) is shown next to the whole-image score, so localized artifacts can be told apart from the global figure.
Comparator: a selectable LPIPS perceptual backbone. The Metric menu now offers LPIPS-AlexNet (the existing fast, lightweight default) and LPIPS-VGG (a heavier, more detailed mode), each downloaded on demand the first time it is selected and verified by a pinned SHA-256. Results always carry the backbone in the label (for example LPIPS-VGG(0.0020)) since values from different backbones are not interchangeable, each backbone keeps its own per-frame cache, and the chosen metric is remembered across sessions.

The app, taskbar, and Start menu icons now render larger within their frame. The SVG masters' built-in safe margin was reduced (the rounded square grows from ~84% to ~91% of the icon), so the artwork reads bigger at every size while keeping the same glyph proportions and rounded corners. Regenerated from the Q1View.svg / Comparator.svg masters.
