Playlist pause button

[SgAkErRu]

Problem

The playlist window has the play and Next / Prev buttons, but there is no Pause / Unpause button.

So, we can switch videos from the playlist window, but we cannot pause/unmount videos from this window.

This is necessary for those scenarios when the main player window with video is on another screen (for example, an image projector), and the playlist window is at the operator's disposal on the first screen.

P.S For example, VLC player provide this functionality with pause in playlist window.

Solution

Add new pl_pause button to playlist window.

Playlist window with new button
