It could be useful to have the coordinates synced on the mouseover event in the bottom, in option.

i wanted to compare the latitude of NY with european towns.

a tool such as a measure tool for distance would be useful too, such as here : http://www.volvooceanrace.com/fr/virtualeye.html (selecting the tool distance, and click on the map.)

i’ve just created an account, i’ve seen that there is a wiki : osm.wiki/Main_Page
