Hello.
Color values in OSM should in lower case.
In general in OSM other than proper names and a few other exceptions, all tag values should be lower case.

Hello.
You changed a playground into a dog park, but the surface is left as rubber. Is that accurate?

Hello.
While your edit is not wrong, generally if a feature has a wikidata= tag then wikipedia= tag is unnecessary since it can be extracted from wikidata.

Hello.
In this edit you moved a library node a few buildings over. Was that intentional?
Also it looks like you tagged what appears to be an apartment building as a single-family house. Could you please elaborate on this change?

If you think that somebody needs to be fixed about a feature that you can't, rather than using note= tag, it's better to use fixme= tag.
If you'd like you can try using https://projets.pavie.info/yohours/ to generate opening_hours tag that matches this biz.

Also while you cleaned up biz tags from the building itself, you left opening_hours= tag on it, which obviously is not necessary for an apartment building.

Hello.
There's no need to add both email= and contact:email= tags. just 1 is fine.
Regarding biz hours, if they are closed to the public on weekdays then tag them as such.

Hello.
When adding facebbok info it's sufficient to use just 1 tag.

Hello.
You can tag this as a vacant business or use lifecycle prefix until the new biz opens.

Hello.
Rather than delivery=partner, it's more correct to use delivery=yes and delivery:partner=* as documented on delivery:partner=*

Hello.
Rather than using shop=vacant, it's better to use "disused:" lifecycle prefix as documented at osm.wiki/Lifecycle_prefix
While your change is not outright wrong, there are some that consider shop=vacant as a bit misleading.

Instead of stuffing city into the name= tag, you are more than welcome to use "branch=*" tag to distinguish individual locations of a chain/franchise/whatever.

Hello.
Nothing specifically wrong with your edit. However, you are using JOSM version that's over a year old. Consider upgrading. 😉

Hello.
Instead of outright deleting closed biz, it's much better to use lifecycle prefixes as documented on osm.wiki/Lifecycle_prefix
Doing it this way preserves history of this object, if there's ever a need in the future to refer to that.

Hello.
In this edit you also dragged intersection node a few houses over. I fixed this.

Hello.
When mapping features please be careful when panning the map around. In this edit you seemed to accidentally dragged a road a few blocks over.

I'll fix this, but in the future, please be pay attention on the changeset submission screen. It shows you what elements you are modifying... If you see something that's unexpected, please double check your changes. 👍
