Quadra v0.6.0

What's new

• New layout. Tools live in a left rail (Perspective, Straighten, Crop), parameters in a sectioned inspector on the right, file info in the top bar and a status bar at the bottom.
• New icon and logo. A flat Q in a squared tile with a skewed dashed quad and a drag handle, replacing the glossy icon.
• Crop now toggles from the rail: click it again, or pick another tool, to cancel.
• DMG downloads. Apple Silicon and Intel disk images, with stable file names.

Install

Open the .dmg, drag Quadra into Applications. First launch: right-click Quadra → Open → Open (the app is unsigned, so macOS asks only once).
