Feature request

Hello, congrats for a great module. Please allow me to ask for two more things, that are much needed, IMHO.

1) It would be great, if we could like in the other locator plugins, state in the admin gui, where our map should be located, centered, zoomed, instead of right now, being centered by default.
2) It would be great, if we had the opportunity, to filter locations, based on distance also, instead of only tags right now.

Thank you in advance
