Thumbnail Grid Studio 1.4.0

What's new

macOS

• Refined the native toolbar layout and behavior across macOS versions and toolbar display modes.
• Corrected resolution metadata spacing and removed the redundant px suffix.
• Hardened the reproducible macOS packaging workflow.
• Updated the macOS application and CLI to version 1.4.0.

Windows

• Improved Windows rendering throughput with a bounded rolling task pool.
• Kept the interface responsive by moving CPU-intensive rendering work off the UI thread.
