17898	better protection of relation member order	skyper	team	"Right now, you do not get any information if you split a way of an incompletely downloaded relation and it is not possible to determine the right position of the new member (before or after) in order to keep the order correct.

What I ask for:
1. a warning that user can intervene and manually download at least one more member. 
 * in #18596 for `type=route/multipolygon` relation a dialog was added but only if the relation is already known/downloaded.
  * the way to determine needed downloads need to be adjusted/changed, see #18863.
   * ~~the neighbors in the relation's member list are used instead of the connected ways in data.~~ see [#18863:comment:35]
  * support for more types is needed see #10808
   * is there any relation which does not benefit from preserving the order and has no special treatment.
1. an option to automatically download one or two members to determine the correct position.
 * introduced for `type=route/multipolygon/boundary` in #18596
  * does not work for all multipolygon see [#18596#comment:60] and needs to be checked for boundary
1. a silent, temporally, partial download of the direct neighbors to automatically find the right position.
 * discussion?

Not sure if you really need both neighbors."	enhancement	new	normal		Core	latest		split way relation order download	JeroenHoek
