turn off the coverage track and set each track height

[baozg]

Hi, @tobiasrausch

Is there any options in wally could turn off the coverage track? If I cannot sort the order of the reads, then each track could be too high for visualization and need to increase to a very large -y. Otherwise, wally will stop after the Image height is too small!.

So it would be possible to turn off the coverage track and set each track height separately?
