A few things:
It would be nice if, after magnifying the data, if I could move the window about with the arrow keys. That would make it easier to scan the data.
Also, when scanning the data, the vertical scale jumps about. That is distracting from the task of actually finding something. It would be nice if the scale stayed fixed. Maybe a check box is needed, so those who like the re-scaling can have it?
The fold tool is quite powerful. But it does not allow for fast changes. If I happen to be way off, it takes forever to drag it to the right fold frequency. A way to speed it up is needed.
Finally, there is this (and many more like it):
Why is that a transit, and not the dip at the left, or the dip at the right? There seems to be no reason, and the game gives no reason, nothing for me to learn from.
