Hmmm, I love OSM, consume their data in my small cycling project and regularly contribute smaller fixes.

But I also shy away from anything more complex than fixing attributes and meta data of existing objects. Especially editing relations, ways and nodes - is this possible with MapComplete? I loaded the Cyclofix map, but I can't even select cycle paths or roads, just edit POIs.

Editing attributes of relations is possible. Adding or deleting objects to relations might become possible one day. Editing geometries is out of scope for this project.

Thanks for the pointer! I posted here before properly exploring the other themes.

Really nice project. Thank you for contributing to the OSM community.

Out of curiosity, may I ask why?

It's not that I have this use case regularly, cycling-related it mainly comes up dealing with tracks through forests and fields.

Excellent question!

First: editing _attributes_ of geometries is totally possible, editing the _shape_ of geometries is not possible with MapComplete.

If one allows to edit shapes (aka: geometries), this means that one can draw or move lines around - for example: add/move a cyclepath. A contributor might thus move a line into another geometry (such as a building). But as MapComplete has focused maps, they might not be shown to this contributor!

Allowing to edit geomtry shapes this implies I should show all _other_ lines and polygons (e.g. forests, streams, buildings, ...) to avoid incorrect intersection.

The point of MapComplete is to keep it simple and focussed on a single topic. Showing all geometries is counter to that. On top of that, we already have an excellent tool which handles geometry drawing: the iD editor you'll find on openstreetmap.org/edit .

One could also argue that creating/moving points (which can be done with MapComplete) could also cause data errors; but the 'add new point'-wizard has some steps to invite to add with high accuraccy. And even if someone adds a point in a wrong location (e.g. in a building instead of outside of it), the impact of a misplaced point is generally way less then that of a misplaced line or area.
