The new “pin” function is not accessible in inspector setup. You can see it in the top right hand corner but there doesn’t appear to be a way to invoke it.
+1 I was excited to stumble upon this as I want the Fader to always be visible, but it doesn’t seem to work.
You mean, clicking in the column underneath it, at the level of the desired tab, doesn’t add the “pin” icon in that column?
(I know these kind of replies don’t really help, but… “it is working here” 
)
No, nothing happens wherever I click.
