@vicmora I like it.
To make it generic , probably should expose the zoom as a variable, in my area I prefer showing a larger area with only major roads showing.

With black background of mirror I also prefer the night mode of this sample: https://developers.google.com/maps/documentation/javascript/examples/style-array

Maybe expose the Style as a variable as well, letting the user define it or leave it blank for default, alternatively you could hardcode a particular inverse colour style, and have a config to enable it.

@billp100 The photo shows your Calendar module with a header that matches your calendar colours, like a legend, which is great. But how did you do that? It is not reflected in the config you posted, unless I am missing something.
