It would be very helpful if the step mode piano roll display showed where bar one ends and the next begins. I am working in 12/8 time (pretty common eg Oxygene) and I am constantly having to calculate bar boundaries. All the piano roll screen shows for this is which screen I am on. So for an 8 bar track in 12/8 zoomed to x1 there are 6 screens and it shows 1/6, 2/6 etc.
Just a small dot or line showing bar boundaries would be convenient. Or maybe some indication of which bar/beat the screen starts at.
It would also be great to be able to scroll horizontally to a bar boundary.
Just a suggestion.
