This is saved only in your browser (localStorage) — everyone who opens this app can set their own home base without affecting anyone else.
If your address geocodes to the wrong spot (common for rural roads where the mailing city/zip differs from the map data), drop a pin's exact coordinates here and the app will use them instead of guessing from the address text.
Save the address/coordinates above under a name, then switch between them with one click — handy if you (or Kurt) work out of more than one location.
You can also paste exact coordinates instead of an address — one per line, as lat, lon or lat, lon | a label. Coordinates skip lookup entirely, so they're the most reliable option for any spot the map ever gets wrong.
