FWIW, I think a lot of the web would profit from a widget like that - so 
if we can implement something like it as e.g. a web component, I think 
there may be some interest in taking this as a base for a web standard 
with an in-browser widget in the future - IMHO, this is one of the 
biggest pieces HTML is lacking to become a really useful UI language
