First of all, thank you for your ideas. None of them do what I'm suggesting however.
CTRL+Shift+H does exactly what you says it does. However, it remains the same size vertically. I need it to display just that track (or tracks that have been selected) and FILL THE TRACK VIEW VERTICALLY
Yes, clicking just below the pan control might possibly cause the track to go full screen. However, it's not what I need in my workflow. That would be fine if my cursor happened to be in that are. However I might be editing all the way at the right hand side of the display and would have to go to the left side to do this. And many times I might be editing something like a bass track against a kick track. I can lasso any portion of both those tracks hit "H" and instantly both of those tracks fill the screen vertically. Regardless of how they are zoomed horizontally. And I can do that with one, two, three, etc. tracks.
If the two aforementioned processes hide all tracks/clips not selected AND fill the track view VERTICALLY with your selection, then my copies of X1, X2, X3 and Platinum are broken and must have come from a different batch. They must have been fresh out of this feature on the day my copies were made.
It may sound like a very nitpicky thing but for me it sums up to many more keystrokes and lots of time. I literally can fly through 8.5 and I can't through Platinum. This one thing has been the reason I haven't utilized X1, X2 and X3 although I own all three.
I will make a feature request for a feature that was already part of this excellent software but obviously this is something that's not an issue for the hobbyist. Or even any others who use this software at the professional level. So, I don't feel too confident that this will get much attention.
Call me crazy but this is how it is in my world.
And again, thanks for your suggestions/thoughts.
Earl
