                        <li>(*) The <b>debug</b> option enables displaying the ID of vehicles, roads and intersections during a mouse hover.
                            <b>This will cause a slower replaying</b>, so we suggest using it only for debugging purposes.</li>

Remove the sidebar and make it a floating box instead. Seperate the stuff from each other (by groups). Replace the cityflow word with Vehicle Flow Customization (make the text smaller). Make sure to keep the (selected) when i click on debug. It is necessary for me to have that info so i know what road/lane/intersection my mouse is on. Info box is not needed
