Can you add option to rewrite links directly on page, so that other scripts (like "YouTube Video Preview and Ratings Keyless") can use these video links?

Maybe you should tell the script's author to fix this problem.
In this case, change the line 787:
From const v_id = e.target.firstElementChild?.href?.match(/(?<=v=)[a-zA-Z0-9_-]*/)?.[0];
To const v_id = e.target.firstElementChild?.href?.match(/((?<=v=)|(?<=\/shorts\/))[a-zA-Z0-9_-]*/)?.[0];
change the line 1123:
From const v_id = thumb.href?.match(/(?<=v=)[a-zA-Z0-9_-]*/)?.[0];
To const v_id = thumb.href?.match(/((?<=v=)|(?<=\/shorts\/))[a-zA-Z0-9_-]*/)?.[0];
It's work perfectly in my test.

Thanks for the help! I'll repost your solution on "YouTube Video Preview and Ratings Keyless" feedback page.
