You've also named one section
just "Tammermaa". I assume it's by mistake.

It's usually better to tag forest paths as highway=path ("Path" in iD editor template selection) unless there is an explicit ban on bicycles there.

The beach is already added and has an appropriate name. Is something missing in your opinion? What did you want to achieve by adding this name here?

Hi, I recommend to check if
tourism=guest_house
is applicable so that it won't be just a building with a name.

You can add
tourism=guest_house
in the bottom of the left panel, under Tags when the building is selected.

Hi, you've accidentally connected Lepistiku park's footways to Tammsaare keskus. It sometimes happens, but when you save the changes, please review all the warnings before submitting. I've fixed it.

Hi, are you sure that your name correction is correct?

"s" is often transcribed as "з" in Estonian to Russian transcription, when the "s" is between the vowels.

Thanks for noticing! I've removed this whole building part, looks like I forgot to remove it when I split it into two other overlapping building parts.

Hi,
1) Since you've already added business as a node, you don't need to add a name for the building.

2) This looks like a legal address. Is any activity done on this address? Doesn't it need to be on the map? OSM is about geospatial data, there is äriregister for keeping a registry of legal entities. Seems like there is also another business registered here this way.

3) If it is useful, the node probably needs an office tag office=* . Otherwise there is no way for data consumers to understand what it is.

:conditional seems to be a key suffix you can attach to existing key to either change the default value or in some cases just show at what condition it's 'yes'. For example
parking:maxstay:conditional=xxx or access:conditional=xxx

"parking" key is used to describe parking types, so while parking:conditional is possible, it could be used to describe a change from "on_kerb" parking to "lane" parking at certain conditions, for example.

Hi, as I understand, based on the same table, the tag should be
restriction:conditional=no_parking @ (Th 10:00-12:00)

There doesn't seem to be a tag named parking:conditional, there is parking:condition, but it's deprecated.

Hi and welcome!
The local (Estonian) name should also be added as default name.

I agree with Pikse here. I wanted to write something like this, but was too lazy to formulate it in such a clear way. The fact that teeregister adds "tee xx" to adjacent road names in other places shows that there is some inconsistency here and IMO it's better to just follow Maa-amet here. Unless street signs on the ground explicitly say differently.

You also can notice that the street itself has no name there.

IMO we should avoid creating a "tree"with branches for streets and try keep them as a simple chain unless official data/street signs say differently.

This is a name of a cadastral unit also containing "L3" in it's name. It doesn't have to be tied to a street name.

Hi, you may consider using
landuse=allotments instead of farmland in such cases.

landuse=allotments

Thank you. Parking is sometimes a problem and residents sometimes don't like when someone else parks near their house, but as long as it's allowed by law, nothing can be done about it and OSM should reflect this reality.

Hi, welcome!
Nice edits.
One thing I've noticed is that you are adding private to many parking lots. Private means that there is some kind of sign which prohibits to park there. Is that so? I've seen some new mappers make such mistakes, so I'm asking just in case since I don't see any signs https://fotoladu.maaamet.ee/etak.php?B=58.82946896978868&L=22.770709492277522&fotoladu

Thanks. I've split the shop.

Hi, do you happen to know anything about node/11207548631 ?

As I understand it's an outpost/pickup point for 01.ee, ox.ee and pets.ee

I've noticed that they have a large selection of pets.ee stuff on shelves which you can probably buy on the spot, so maybe it's not just an outpost for pets.ee ?

What do you think if create separate nodes for the shop=pet and shop=outpost even if they operate as one facility?

I'm not really sure what exactly are you referring to and what roads you speak of.

I've changed back road types on one of your changeset since you've changed them incorrectly. If you are referring to this, then highway=track is for LAND access roads, while roads leading to houses be at least highway=service. Refer to the wiki for more information.

If you are referring to something else, I have no idea what are you talking about.

BTW, history in OSM is not erased, you can check it out if you want to find out who this someone is and ask a question.
