The logs panel is both collapsible and resizable. By clicking the gray bar at the top, you can minimize or restore it. In addition, by clicking and dragging just below this bar, you can resize the logs panel to any height you want. When collapsed and restored, the logs panel will remember this height and restore back to it.
