Suggestion: properties: monitoring graphs

When editing the monitoring tab in properties to change which graphs are shown, the list is long, but the box is small, it's very difficult to move things from one end to the other. Dragging off the end of the list makes it move very fast, otherwise I'm limited to moving 6 spaces at a time then scrolling a bit and repeating. Please add a method of for example moving an item up or down one space at a time using for example ctrl and up arrow on the keyboard. Or allow the dialog box to be enlarged.
