FR: Improve trackpad zoom behavior to match macOS conventions. Adjust trackpad zoom sensitivity

[greetclammy]

Current Behavior

When using a macOS trackpad to resize images with Image Toolkit, the zoom in/out behavior is notably more aggressive compared to standard macOS applications. A small trackpad gesture results in a disproportionately large zoom change.

Desired Behavior

1. Primary Request: Adjust the default zoom sensitivity to match macOS conventions

   • Provide smoother, more controlled zoom transitions

2. Alternative Solution: Add configurable zoom sensitivity

   • Allow users to adjust how much each scroll gesture affects the zoom level
   • Add a sensitivity slider in the plugin settings
   • Potential settings:

     Zoom Sensitivity: [Low] ---|●--- [High]
     

Benefits

• Improved user experience for macOS users
• More precise control over image viewing
• Better consistency with platform conventions
• Reduced frustration when working with images

Implementation Notes

• Consider using the native macOS scroll/zoom acceleration curves
• Could reference Safari's image zoom behavior as a baseline
• May need to adjust the zoom multiplier applied to trackpad gesture events

Additional Context

This improvement would be particularly beneficial for users who frequently work with images and require precise control over zoom levels, such as when:

• Examining image details
• Preparing documentation
• Comparing multiple images

Environment

• OS: macOS
• Device: Magic Trackpad
• Obsidian Version: 1.7.4
• Image Toolkit Version: 1.4.2

Thank you! 🙏
