How hide playlist window...?

I would like to hide playlist window - now I need press 'l' every time I run mocp. Is any option to add to config file to hide playlist...?

Just past Layout1 and Layout2

Just past Layout1 and Layout2 options from the example configurations file (those described as default configuration) to your ~/.moc/config, but exchange their values.

Maybe I do not understand

Maybe I do not understand what you want to do, but can't you just remove the playlist window from the default window layout ?
