[Talk-GB] Envelopes map

[Ken Kilfedder]

This works well for me - though it slows the browser to a crawl in densely-mapped places!

Do you think it would be worth adding something for addr:flats ranges?  If there is something like addr:flats=1-4 or =1;3;5;7, you could pick the first (or last) number and add a row "Flat X".

E.g. for node 8904420166 , it could generate:

Flat 1
Barrett House, 
7 Temple Mills Lane, 
[TOWN/CITY] 
[Postcode]


It might also be useful to have a hyperlink to the object with the address tags, so that any flaws on the 'envelope' can be corrected.

This doesn't change my conclusion from 9th Jan that addr:substreet is needed to provide certainty to those data users that need it and cannot rely on attempting to automatically adjust for mis-use of addr:place. But for now, it is working on add:place so see it more as a QA tool rather than a final product.
