Works great! :) Could you add this to the local CSS?

.dataLayersDiv {
	height: 20em;
	margin-right: 1em;
	overflow: scroll;
}

because the overlay list is too long and some of the languages are off the 
screen.

Not sure whether it is appropriate for this list, but I was thinking on how to 
properly cascade languages, without coming to a full conclusion.

First, if I am watching Serbian layer, and there is place that doesn't have 
Serbian name, but does have Croatian name, I would prefer to see Croatian 
name instead of the "main" name. There probably are more such cases 
(Nynorsk/Bokmal?). (I see you are not rendering those but I guess you will 
eventually.)

A harder problem is that for some uses, users might legitimately need to 
display several languages. For example, there is this square in Belgrade that 
has:

lang=Трг републике
lang:sr at Latn=Trg republike
lang:en=Republic Square

A tourist from USA, viewing a map of Belgrade, will want to have all three: 
the first is actual name of the square as actually written on the street 
signs on the square (which he needs so that he could read the square name on 
the signs and verify that he really is there); the second is transcription of 
the name to Latin alphabet (which he needs so that he could know how to read 
the square name aloud so that he could ask the locals how to get there); the 
third is the English name of the square (which he needs to ask the 
English-speaking locals how to get there).

I am not sure how to display all of this without drowning the map with text, 
and I am not sure how people would choose what they want to see (maybe 
someone who is not traveling to Belgrade but only looking at the map would 
prefer to see only sr at Latn and English?).

If this is implemented, next step is automated transcription...
