text: restored pre-pokeymon tag.  it's a multipolygon import and a good candidate for micro-mapping, as well as no doubt updating.  seems some inners have their own tagging as well.
  
  it looks with my tablet screen resolution that z12 covers the entire thing.  i know iD will abort the ability to edit below a certain zoomlevel, 13 if i recall.
  
  my potlatch session does in fact not display anything but the selected way once i reach z13, loading by default all map data to z14 and in the process ballooning to more than 50% of my memory usage (p1 typically starts at 1MB).
  
  I believe JOSM lets you selectively load items which could help here if memory use is a problem - the separate flash child process is very useful to catch early and sacrifice when it starts running away, before responsiveness turns into tens of minutes lag of thrashing.
