Playlist management on iMac version?

Hi,

I am on version 5.1.3. and there seems to be a pretty big difference in the way playlist can be made.

On iPad I am able to Add from Library and Add from Files, etc. via the little triangle besides the [number of songs].

But not in the iMac version.

I looked everywhere, but still didn’t find out how to import from Library and From files into a playlist in the iMac version of Djay?
