I'm trying to replicate [this](https://i.imgur.com/JNswW.png) ncmpcpp configuration

![ncmpcpp config](https://i.imgur.com/JNswW.png)

found on [ArchLinux BBS](https://bbs.archlinux.org/viewtopic.php?pid=1113439#p1113439).

It features a double-paned playlist window: on the left it shows a classic playlist, on the right there is a file browser (by default on window 3).

On the entire internet this is the first time I see such config, and I'm trying desperately to emulate it, without success. I've already tried tmux, but this seems far from a `splitw -h`, since the upper and lower parts of ncmpcpp are perfectly integrated with both panes.

Any hint?
