I've tried to map the internal courtyard in this hotel by copying the use of inner/outer ways in a multipolygon in other buildings.

But it doesn't seem to get rendered properly. Can anyone fix it?

There's a large administrative boundary called "Yahoo hires imagery in Ireland ..." I only know this because I can see the title rendered (in the centre of the area) at certain zoom levels on OSM.com. I can also search for the title and get a result form the nominatum.

The area covered is too large to see in a zoom-in edit area in Potlatch 2. So how can I view/edit this way? Even being able to view the list of nodes and history would be partially useful.
