Wikipedia has a small village around here named 'Nixon's Corner'
https://en.wikipedia.org/wiki/Nixon%27s_Corner
which is based on 2001 NI census.
Maybe it no longer / never existed?
If there was a former checkpoint of same name situated here would it be good to tag with some sort of 'historic' tag?

Is there really a village called Clonmacnoise here? Wikipedia says it's a monastery (and tourist site). This looks like it came from an automatic import of the place name data, and am doubtful it should be categorized as a modern day village at this spot.

There is another Lislea townland in south county Longford at osm.org/relation/2438828#map=13/53.6035/-7.7450

Just wondering if either are a mistake?

Northside Enterprise Centre is tagged as a shopping centre - are there any retail businesses in it, or is it more offices? If the latter 'shop'->'mall' can be removed

Has a service area (highway->services) been built here? National Express seem to have a stop entitled 'Grantham Service Area'

This doesn't feel like a Coach Station - is it a travel shop which sometimes has coaches pick up outside? If so remove amenity=bus_station and add a bus stop node outside it.

What is the name of this Park and Ride?

Marked as 'Canal Bridge' on Citylink timetable. Don't think this is a Canal. Any local knowledge?

Any idea which 'Barnham' is the canonical village? The node at 29382615 or the way at 163365403 (which seems to encompass Eastergate village node).
