Show/Hide Track Icon
Available in Mixer windows. Show or hide the track icons in the channel strips. I often keep them off since I color code tracks, regions, and channel strips. I will probably adjust this more when using a laptop. Something about screen real estate.
The state of display is “per window” so changes to a mixer window in screenset 1 does not effect mixer windows in screenset 2. This is handy. The mixer panel in the main window and a mixer window are two, independent displays. The command affects only the mixer window that currently has focus.
Channel strip controls in Logic Pro — Apple Support
Control-click a portion of a channel strip not containing a channel strip control and in the Channel Strip Components submenu of the pop-up menu choose a control to display, or deselect a control to remove it from channel strips.
