P2 can, at least. Other people seem to suggest that iD does a <br>

P2 and ID are aware of relations and can do a few basic things like adding/removing a way and shifting a way up and down, in one relation at a time. If you maintain a lot of long distance routes, that is painfully inadequate. Even more so if you try to do it in a way that prepares the relations for data users, currently meaning linear and gapless gpx-es for use in navigation software, elevation profiles, and trip planners. You need validation, gap detection, multiple relation windows with shifting between windows, sorting, jump to first/last member, direction reverse, download all members even those not in the bbox, ... </div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

The more interesting question, though, is "why do you want walking route <br>
relations to be sorted". The point that's already been made about <br>
routes that use the same way twice is a valid one, but almost never <br>
applies to walking route relations. What are you trying to do with e.g. <br>
<a href="https://www.openstreetmap.org/relation/1976184" rel="noreferrer" target="_blank">https://www.openstreetmap.org/relation/1976184</a> (the part of E2* that <br>
runs through Yorkshire) if it's not sorted?<br>
<br></blockquote><div>If it's not sorted: display only. If I want to walk it, I want to use OsmAnd navigation and or Garmin navigation. OsmAnd and Garmin currently cannot use the relation directly, so I have to use a gpx, and they recalculate the route for navigation. The gpx needs to be continous, sorted and gapless, or it won't work. Overpass and Waymarkedtrails can export to a routable gpx, if the relation is one sorted and continous chain of ways.</div><div>So before exporting, I use JOSM relation editor, load the entire thing, solve all gaps en remove duplications, move alternatives one or more separate relations, then export the main route as gpx. </div><div><br></div><div>I also notify the operator of the website <a href="https://www.longdistancepaths.eu/en/" target="_blank">https://www.longdistancepaths.eu/en/</a> </div><div>so he can use the export for his trip planner. If he could depend on routes to be flawless in OSM he could connect directly to it for automatic periodical refresh. </div><div><br></div><div>If the route is on that planner, I would probably use that first to plan the trip and route according to train and bus stations, hotels & B&B's, and places on the way, then export the trip gpx from that planner.</div><div><br></div><div>I will actually have a look at the E2 Yorkshire thing after lunch. I can repair technical problems. If I need local survey I can probably not fix it completely. Have to look at the history as well, don't want to offend mappers over there with foreign ideas. </div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

* There are actually many other things wrong with that relation. It's <br>
not signed, so in a since here it "does not exist" but at the very least <br>
it should be tagged as such. Also it's actually defined here in terms <br>
of the Wolds Way (which is signed), not in terms of individual paths. I <br>
also doubt that the LDWA is in any sense an "operator".<br>
