Make play list more narrow

[scootergrisen]

When i have the play list on the left inside SMPlayer window i would like to have the video image big and no black boxes above and below but the play list width seem to have a min-width which i guess depends on the amount of icons at the bottom of the play list.

I would like to be able to make the play list even narrower.
Right now it almost takes up half the screen.

Using SMPlayer 16.8.0 + Qt 5.3.2.
