After seen several boundary relations left open by editions made with iD, and the users which did the changes say that the boundaries relation are not shown in iD, I did a test and it seems that iD does not warn when a relation is modified.
¿Anyone with the same problem?
¿Should iD be modified to warn the user about some changes, or to disable doing those changes?
IMHO we **urgently ** need an update on main site osm.org with an improved version of iD … the one available today is still 1.0.1 that is some months old, I think.
