I modified results_list.php, line 99, to:

CODE
if(!isset($order) || ($order == "miles"))


And added to templates/results_list_format.htm, line 17:

CODE
<option value="miles">Miles</option>


(I used the program's Imperial units, but this could be internationalized.)

This essentially just adds a no-op pass-through option for the default results list order. No major effort at all, but maybe someone else will find this useful. (That is, if Brian tells me that I'm not breaking anything...)

Also, I removed both options for name and address sort. For my use, sorting by name didn't make any sense since all locations have the same name/title. And sorting by address doesn't accomplish anything either, since no two locations are on the same street/hwy (how does 123 Elm rank versus 321 Maple?) But, sorting by city, mileage, and zip will allow our users to quickly organize their results in a relevant format.

Actually, sorting our nationwide locations by state would help too... hmm, more later...
