Odysee Enhanced Autor: cst8t

Adds useful viewing controls to Odysee video pages, including a theatre mode that dims the page around the player and a loop tool for replaying either the full video or a custom start/end segment. The controls are designed to feel native to Odysee, stay out of the way when not needed, and work smoothly on dynamic video pages. Hope to add more features in future if I (or anyone else) have any ideas for things wanted.
