I love the tempo map. For I like to make improvs.. and I hate playing with metronomes. So this gives me a way to convert my improvs to midi that is measure aligned.

But what would be even cooler is that if one could just click and drag the measure lines in the notation window to do the same thing.. i.e. moving the measures changes the tempo map and hence the way the notation is displayed. A feature like this would enusre i buy then next upgrade for sure!
