Had a blast this hacking away this weekend, almost have an end to end #osm editor.
Have POI download, super primitive add and edit and really close to getting the upload complete.
osmChange XML format added a bit of complexity, but I'm really pleased with my GeoJSON and JSON Patch setup for representing data internally.
Excited for what I can knock out in the next few nights. Once all of this scaffolding is done I can really start to experiment with user experience tweaks 😁
