Where exactly do you grab to drag? What is the button combination for zooming out? +/- for zooming in/out and video - link. It helps if there is a tempo discrepancy. Useless, when notes are squished randomly.
In those scenarios in EOF i prefer to grab the last bit of an imported guitar tab and to drag it all the way to the end of the song. Zooming out makes it faster. In most of a time it solves a problem for me.
