your are still able to drag the lines with your mouse or move them with the cursor keys. as well as having numerous comparison cals showing. not sure i understand what you "miss". i do agree that there is alot of wasted space on this layout and think changing the "display scale" to maxing out at 32k vs 64k makes alot of sense. in fact i think the earlier version of mptune use to only go to 49k. i'll look at changing that so the "resolution" is higher. maybe even have it be a setting you can change.
