Problem Description

Youtube displays how much time is left until a live stream / premiere goes live along with the exact date and time. This makes it easier to tell when the video starts. This is very useful when it's scheduled a couple of days in the future.

Freetube currently does not display this.

Proposed Solution

Display how much time is left until the live stream or video premiere goes live above the exact premiere datetime. This would make it easier to tell at a glance when a live stream/premiere will start and would be similar to how it looks on YouTube.

AFAIK Youtube only updates this text when the page is refreshed so the Freetube implementation doesn't have to be any more complicated than that.

Alternatives Considered

I've not considered any other alternatives.

Hmm YouTube does actually update the text automatically, must have missed it or something.
