I have a feature request I think could help a lot of editors especially in areas where the map hasn't even been looked at. Here in Pennsylvania we have a lot of rural areas, many of which have never even been touched since the base map import. To help identify these areas and get them properly updated, I would like to see a feature kind of related to how Tomnow.com operates. The feature should remember which areas a user have visited/edited each time they return to WME. Now, I know WME Colour Highlights can do this to an extent but its easy to get lost in finding areas you might have missed especially if you are editing an entire county, but if the map was broken up into tiles and the tiles could be blacked out by an editor if they were edited already it would make editing the map a lot easier. Additionally, I would allow the feature to see areas untouched/updated by any editor and individually. The feature will only black out an area when viewed or edited at zoom level 4 or closer, maybe incorporate a time limit too to deem which areas have been updated by other editors, edits older than 1 year should be rechecked.
