This script has some minor changes, mostly cosmetic, some visual bug fixes on certain objects on screen.
1.- Some videos have "borders", I know many hate borders and prefer them not to exist, that can be customized from the script itself. Although currently they are at 0.01px (thickness) so they only look like a tiny line to differentiate between the rest of the background and the rest of the objects.
2.- Moved the action buttons below the player ("like", "dislike", "share", "download", etc. They are now centered instead of being at one of the two ends. I did this to avoid having one of the two ends empty with no button.
3.- Added a script to convert "short" videos to normal videos, and now these play in the normal YouTube player without very large or very small dimensions.
4.- Added some rules to prevent videos with very large dimensions (which extend the player so much that they look like "scrolls" to navigate horizontally) from breaking the page and its elements. Now any video will ALWAYS use the native size of the YouTube player (709x397), this does not affect the image quality only the size of the player.
5.- The script is compatible with the "ratebar" of many extensions similar to "return dislike", I have also experienced some bugs with some of those extensions, it is not a problem of the script but of the extension itself, so I recommend checking the extension you use to avoid misunderstandings with the script.
Note: Because I am a newbie in script editing (I DID NOT CREATE THE SCRIPT, I just edit it and fix some issues with the help of AI), I may not be able to "update", fix or remove some bugs, due to my inexperience, however, the original author is still active, so since this script is just an edit, it MOST LIKELY shares bugs with the original that I cannot fix, in that case you can go to the original author.
