Shotnix 0.20.2-beta

Changed

• The post-capture thumbnail now fills its card edge-to-edge, CleanShot-style: center-cropped when the capture's shape differs, zoomed to fill when the capture is small. Previews are pre-scaled with high-quality interpolation in the capture's own color space, so small text in menus and dialogs stays crisp.
• The post-capture overlay floats higher on screen, comfortably above the Dock, instead of hugging the bottom corner.
