Playing a single file adds all tracks to the playlist - Intentional feature ?

When I play a single audio file from the list of available tracks, everything is add to playlist. I wish that only that particular file is added to it.

As a small workaround, you can use the + button to load that music only into playlist and play. It’s a lot of clicks. It would be easier with single click.

Is this feature intended by the developer. Because I am trying to open a KDE bug ticket with “wishlist” tag. Hence why. Asking here beforehand.

Ain’t that annoying for you all ?
