### Problem Description

Bottom bar hides part of a video. The problem is in the screenshot: i specifically paused the video to see in detail which command the person entered, but nothing is visible because of the bottom bar. If there is a way to hide it - i did not find it.

### Proposed Solution

Hide bottom bar when paused. "Close" button, timer, whatever.

### Alternatives Considered

None.
