Hi Matti.
First of all thank you for the great add on!
Just curious, is there any chance to have a graticule as an overlay over the base map? There are some LeafLet graticule extension, like this one, for example: https://github.com/Leaflet/Leaflet.Graticule
Is it possible to plug them in into V-Leaflet in some way?
I’d expect creating an add-on to support Leaflet.Graticule should be quite easy to do.
I’m quite busy currently so can’t promise to do it as a hobby, but via Vaadin’s support service that should be rather quickly done by some of our experts.
