so you say, since these commands aren't invoked often, it's good to bury them and make them less accessible?
changing volume while watching a movie, 2015: rest your fingers on the keyboard on top right, press the correct buttons.
2016: look down, tap on the volume icon, tap again and slide your finger on the volume bar that appears.
that looks like a downgrade to me.
if the gains are minimal, since all the tasks i can perform were already there (with keyboard shortcuts), then overall it's a downgrade. also, if you're using windows, the loss of physical f-keys is another downside.
