Greasy Fork is available in English.
Instant video previews in popup player by hovering or clicking video thumbs. Video ratings and resolution data no longer shown on the thumbs. This is a fork of Costas' original with Arantius' GM4-Polyfill js.

Correct - YT no longer displays likes/dislikes until you click on a video. I will modify and rename this script.
Ratings not working March 2020
When I installed this in March 2020, I found the ratings display does not work and it's not possible to disable options using the control box. I understand that there were changes made by Youtube in February 2020 that have broken a number of third-party scripts so this script probably suffered along with them.
