Add "Pause/play on double click" option

[david419kr]

Description

Add a new configuration option "Pause/play on double click" that allows users to trigger pause/play functionality with double click instead of single click.

When this option is enabled:

• Double click pauses/plays the video instead of single click
• "Prevent pause/play from triggering on double click" is automatically disabled to prevent conflicts
• "Disable fullscreen toggle on double click" is automatically enabled to prevent fullscreen conflicts
