When symbolizing features using Quantities (Symbology tab), I would like to see a "COUNT" field next to RANGE and LABEL to show how many features fall into each range. And show this "count" in the legend in the TOC and map layout legend with a toggle to show/not show.
Also, if symbology values change, such as date values that change daily, the symbology would auto-update w/out having to go into the Layer Properties>Symbology dialog, click the Value field each time to update the layer.
