When maximizing a timeline window with the "Maximize or Restore Frame Under Cursor" command, the audio level meter should be present, or an option to "gang" a second window to the current being maximized in some fashion. This makes detailed multitrack audio editing/mixing extremely difficult without setting up an entirely new workspace. With more than 30 audio and video tracks present almost becomes essential to work with timeline maximized at times.

Switching between workspaces is not 100% reliable and have encountered crashes when doing so in macOS 10.14.4 18E226 with PPro 13.1.2. Build 9.
