Allow Larger Video Area When Using Both Bottom and Sidebar Subtitles

Hi Language Reactor team,

I have one suggestion for improvement. When watching uploaded videos using both the bottom subtitle and the side subtitle panel, the video window becomes quite small—occupying only about a quarter of the screen. It would be great if there was an option to enlarge the video area or adjust the layout so that the video can take up more space while still keeping both subtitle panels visible.

This feature would make the viewing experience much more immersive, especially for learners who rely on both visual context and subtitles to improve their comprehension.

Thank you again for your amazing work!
