I've said all this before: while editing relations in iD is technically possible, it is tedious and difficult in the opinion of many. A great many existing relations have also been broken by people using iD (I can't count how many I have personally experienced). I find editing relations with iD to also be a "nightmare," but I don't want to so viciously disparage iD, even as I do want to discourage others from using it as a reliable, suitable, comfortable, intuitive relation editor. (It is not).
That said, if you are going to edit relations (from this thread: streams, waterways, coastlines, islands...but also many other more-sophisticated and complex-structured data) within OSM, please do so using an editor that strongly supports good relation editing. I use JOSM and recommend it, though I realize that JOSM is not everybody's cup of tea, either. Think: if you know nodes, ways and tags, but not relations, yet you want to edit data properly entered into OSM using relations (and which should ONLY be entered into OSM using relations), you must be able to edit relations. And do so well, without more than the occasional minor error. OSM is not your sandbox for practice learning how to edit relations (poorly), though you are likely to do exactly that (in my opinion) using the iD editor to edit relations. The map does not benefit by sloppy relations being entered by iD (or any editor). Learn the basics of OSM. Next, learn "about" relations (their structure, conventions, the differing flavors of them...). THEN learn HOW to edit relations using an editor that supports editing relations well, such as JOSM. Though JOSM has a learning curve, it is worth it. I do not consider iD to be a strong editor for relations, these are my opinions.
