Thanks guys, I thought my little comparison screenshot was going to be ignored.
But Mike, I actually like track icons.

When I have a lot of tracks going, I can assign nice distinguishing icons to them to easily see what's what.
And that shot was essentially a non-customized quickie default of both setups. I'd normally do some widget re-arrangement to make the layout even more useful for me in 8.5. No amount of re-arranging can save X1. The cramped, minimal spacing of X1 is hard coded.
One thing that wasn't pointed out was the change of the record button from 'R' to 'Red Dot', and automation read from 'RD' to 'R'. I can't tell you how many times I've tried to arm a track in X1 by pressing the 'R' button. Really bad change.
MSR are great choices for button labels. RDW was perhaps less so, but a better solution would have been to maintain MSR and make the automation buttons have a little squiggly 'automation' graphic along with RDW kinda like the old 'select envelopes with clips' button.
