This has been requested many times over the years and is the one of the biggest time killers/click-and-navigate-adders with Cubase for me (and clearly others): In all other DAWs I’ve seen or used there is (at the minimum) a volume and pan control on the header for every kind of track. Having to click first on the header, then navigate over to the inspector, then sometimes have to click again because the right inspector page isn’t open, than finally click on and adjust the volume or pan, vs. simply clicking once on the header of the track and directly adjusting pan or volume (and many other controls in some other DAWs) on the track header is a night-and-day difference in speed and fluidity.
For those who for whatever reason would like to click and navigate more, it would be configurable as all the other track controls currently are in Cubase. Many other DAWs have even more options than volume and pan for the track headers, such as inserts, sends, etc. – and again, all configurable so if you don’t want to see them you don’t have to.
Whenever I use Pro Tools and some other DAWs, this issue in Cubase stands out greatly.
