Can you add the "address find" feature as a part of the extention for site viewers to be able to find locations of their choice?

I think it can be done in this manual process...
--->You can do a search (placed on right top)
--->You can also add your location/address by clicking on 'Add Place'

Thanks for shifting this to the tutorial section!
