Hi McLiquid,

sorry, something in my matching of usernames to real names must have gone wrong and I must have confused you with someone else.

I now realized OSMCha and Achavi run into size issues with changesets much sooner than I expected, so I've changed my Wiki addition to this:
"Many more advanced changeset viewers (such as OSMCha, Achavi, Changeset by Comparison Visualization) are available through the browser plugin OSM Smart Menu which allows opening a changeset in another tool from the changeset view on www.osm.org. As of December 2023, OSMCha and Achavi often cannot load changesets spanning the size of a middle-sized country (or roughly 350,000 km²) and possibly also changesets smaller than that, while the tool Changeset by Comparison Visualization has no problem opening and viewing even worldwide changesets. Since these tools can have different functionality and use cases though, keeping changesets small allows using a bigger variety of tools."

So I'll keep changesets smaller since it's something I can easily control in JOSM.

Wishing you happy holidays and a good start into the new year as well!

All the best,
Paul
