It used to be that when one moused over an electron-flow arrow, blue boxes would appear that illustrated the sources and sinks of that arrow. This feature appears to have disappeared; now, all that appears are the blue circles at the beginning and end of the arrow. Please restore the original feature; it's essential for figuring out if one has incorrectly drawn an electron-flow arrow.
