The Store Locator app could use the option to search whichever starting address you want instead of just the default process of using your current location as the starting point for getting directions. This will allow customers to plan out their trip from whatever location they choose instead of assuming that you are always currently in the location that you want to be your starting point for your directions.
Yes, definately needed. These geo-location requests now cost valuable money for websites/web-masters, and the location is not usually correct especially for computers and also mobiles. So should allow for a custom starting address, thanks!
