Is this a server-specific feature?

Not server-specific

What do you want to be added?

The current seek bar in the bottom player feels a bit too narrow, especially on wider desktop screens. Because it's short, trying to click and scrub to a specific part of a long song can be a bit difficult and requires too much precision.

It would be awesome if the seek bar could scale to be wider, or if there was a setting to let us adjust it.
