Hello everybody,
   I'm wondering if there's room to customize short-text question with Leaflet Map View.
I'd like to: alter default geocoding form, add custom WMS layers, add waypoints taken from another subquesiton question, and so on, everything you can imagine.

Do you have some advices about it? Is there some example code to share?
