I often find myself zooming out in IGV to fit the entire graph, and then wish to follow how the graph evolves through phases. However, that is not currently possible as the zoom level resets to the default when switching graphs. A workaround is to select boundary nodes in the graph, which sets the zoom level to fit all selected nodes upon graph switching. It would be nice if the default when switching graphs with no nodes selected is to adapt the zoom level to fit all nodes in the graph.
