You could set the command to the status bar double click action.
Preferences - Display - ColumnsUI - Statusbar - Action to perform...
The commands name is:
View/Columns Playlist/Activate Now playing
Of course you can make it a keyboard shortcut or whatever. Like any other command...
I guess this is by default. I had same problem few days ago ^^ Just click status bar.
