I'm not sure what the difference is between nodes 313715723 and 7108944 but if they're the same they should be merged, if not it should be made clearer. Also, both seem to denote an area, but one of them shows as just an orange circle on the map.

Guayana Esequiba is also called Essequibo in various sources, so it would be nice if it actually showed up in the search results if you look for that term. See e.g. https://en.wikipedia.org/wiki/Essequibo
