Nice fix for nonames, was this some automated change?

There are some small strange things like Aru loosing wikidata
way/8016649/history

Not sure that this road should have lost tracktype way/641957435/history
Of course it's a bit confusing since it's not a track anymore, but I think it should be ok to have it since highway tag is about purpose of the road.

Tasuja pst way/30908948/history
1) highway=footway and bicycle=designated are uncommon tag combination which should be avoided, this I've fixed right away
2) Tallinn GIS thinks this street does have a name https://gis.tallinn.ee/veebikaart/ (I'm not sure if anyone has asked permission to use their data, but that can be done). I'll try to check if there are any street signs.

You can also check why the highway type was changed here changeset/130798351

Bicycle parking is on the side of the square and can also be accessed by pushing your bike. I'd say using access tags which are about access by law for the whole square is wrong.

I ride bike a lot, but as a pedestrian I don't like sharing infrastructure with bicycles and we shouldn't direct bikes to places where they don't belong. Bolt cyclists often don't care about safety at all. So I'm not sure about Tammsaare park too. I don't want to be too correct with access tags either, but my common sense is a bit different.

Hi, why did you add bicycle access to Vabaduse väljak? It's explicitly forbidden https://www.mapillary.com/app/?pKey=658363728461940&lat=59.433158900883&lng=24.744026637781985&z=19.9&focus=photo&x=0.7973632509441009&y=0.3944349350242621&zoom=1.9419607394178495

and are there signs in Tammsaare park allowing bicycles?

I've merged those ways back. In this place pedestrians and cyclists compete for space all the time anyway. Also added a service road. Now routers which prefer common use roads will use Pärnu mnt and routers which are ok with a bit of walking can use footways there.

This bicycle road actually makes more sense if you route from Estonia theater to Mere pst as there is a bike lane from that direction. Not really sure you're allow to cycle in Tammsaare park. This should be validated.

This looks like a mistake

Please don't blindly ignore warnings.
It's very hard to find things you broke after you've uploaded them
Here you can see for yourself that the road is broken
node/5919256005

Here a parking multipolygon got broken, it's not closed on the building's side

osm.wiki/Relation:multipolygon

Don't you think that way/1155390146 looks a bit close to the cycleway? I think that having one way for bicycles and pedestrians was better there.

And here you drew footway on top of the red bicycle way
way/987191896

Hi, when modifying road geometry like on Priisle tee / Ussimäe tee junction please take care of the bus routes. Judging by another changeset something had to be fixed
changeset/133701785

changeset/132946487
added by dgmapping

For some of the gardens you've added there is also a good tag
landuse=allotments found under garden allotments. Doesn't necessary make your leisure=garden invalid.
landuse=allotments

Nice!
Consider adding highway=path. "terviserada" in the name seems to suggest that this trail is used in summer also.

Hi, you've removed
highway=footway from here. But I assume you can still walk here at least in non-snowy weather. Map shouldn't be changed back-and-forth every season.

highway=footway or maybe highway=path should probably be returned

Judging by aerials it's a pump track and bicycles are the main way to use them (you can "pump" with your weight instead of pedaling)

https://en.wikipedia.org/wiki/Pump_track

cycling=pump_track seems to be used 313 times, don't see the reason to remove it.
sport=cycling suited this better too than skateboards, though both can be present.

Maybe someday I'll try to change pump tracks in Estonia to somewhat similar tagging. (my last change to track just added some tags)

Where did "Laiaküla mänguväljak" name come from?

The landuse=commercial could stay as it is correct. It doesn't need a name or an address though.

under point number 3 I meant that you don't need that kindergarten node at all. Kindergarten already exists as an area way/783376505
and there is no point in having both. I've removed it.

Not sure mapping private water wells is a good idea. Some details on private property should remain unmapped. It also reveals information that you've been to that yard.

osm.wiki/Limitations_on_mapping_private_information

See different values here
traffic_calming=*

Some speed bumps you've added are actually traffic_calming=table. You can edit this value at the bottom, in Tags section.

speed bumps are usually mapped as one node which is on the road.

I'm not sure how to interpret ways.

I've added a node.
node/10683366989

IMO current tagging is not great, but better than nothing.

It would be nice to have SOME feature named Vooremäe and/or Vooremägi. Forest isn't a very good one.
