popup menu at the end of song titles
There is a self-appearing button that positions itself directly after the song name of any song I hover my mouse over when itunes is in songs list view.
The button's appearance is a circle with 3 dots inside the circle. The button is presented for any song(s) selected in the list, and whatever song row the mouse is hovering over. Clicking this button invokes a short menu of options: Add to Playlist, Add to Up Next, Start Genius, etc. Delete is the last option. Basically it looks like a subset of the options you get when you RMB click over a selected song row. Hopefully this identifies the button I'm referring to.
My questions are, what is this button called, and is there a way to turn it off?
