Oh, thank mr. @mstenta
Nice to get your feedback late, I was not checking email notified in a short period.
Just finished it with 3.0.1 update from your team!
Integrating maps with detect location button, adding layer via Mapbox/similar, sync with mobile device is the next step I think (even how to set translate function to translate for native people like: Vietnamese/Khmer/Laos language might be challenging 
)
Again, thanks a lot! See you on Element * | farmOS
