Faster injection on YouTube search results

Version 1.5.5 improves how the Watch Later button is detected and inserted on YouTube Results pages.

The button still appears in the same place as before, but the extension now uses a narrower set of selectors for /results, which reduces unnecessary DOM scanning and makes mounting more efficient.

Same placement, less overhead

This update does not change the visible position of the button in search results.

Instead, it focuses on the internal logic behind insertion:

• narrower card targeting for Results layouts
• more direct menu container detection
• less redundant selector work on repeated observer passes

Better resilience to YouTube layout changes

YouTube often serves slightly different result card structures depending on experiments, account state, or UI rollouts.

Version 1.5.5 keeps compatibility with the main Results card variants while reducing the amount of broad matching used during injection.

Maintenance improvements

• improved internal separation between Home and Results injection logic
• cleaner mount resolution for search-result cards
• small performance-oriented cleanup in the content script

Version 1.5.5 is a focused maintenance release aimed at making the Results-page experience lighter and more reliable without changing the one-click workflow.
