Is the feature gone where you can put the cursor over the coloured part of the track and scroll through track colours by pressing alt and scroll?
I want it back! 
Hi,
This is highly discussed here in the forum.
Yes, this feature is gone. Give over the track name in the Inspector and use the nurse scroll wheel here, please.
So the option to also select a few tracks, right click and choose the option to make all selected tracks the same color is gone as well. Any workaround for that? Thanks
