Hi. Are you sure your new restaurant is not a duplicate?
Location below is correct:
node/12309485965

Hello. Thank you. Fixed: changeset/173289764

Hi. Are you sure there is no entrance with number "7"? Only 7a, 7b, 7c?

This shop is at incorrect position:
node/13141224171

Please use Esri World Imagery, it is the latest image available. Mapbox is quite outdated

Hello, this was a mistake. Thank you for pointing it out.

This is a smoking bar, according to a sign outside.

This ATM node is inside a building under construction, it should probably be somewhere else node/12694749375

Hi, I didn't find any signs with entrance numbers (Ulaz 1-4), only with addresses (19-19v). Do you mind if I remove it (name and int_name)?

Hi, there are no strict rules about foreign names in local community (they didn't discuss Russian, but an idea of using name:en was denied), but usually the don't add it and consider it meaningless. You may start a discussion on a forum if you want:
https://community.openstreetmap.org/c/communities/rs

In my opinion, the translation doesn't make sense at all due to the similarity between Serbian and Russian.

Hi, please don't add "улица" to "name:ru" for a streets where tag "name" doesn't contain "улица"

I removed tag "access=no" because this way is walkable now

Please don't remove addressees from the OSM. I spent my own time to research it.
Example:
node/12196980136/history

I may try to fix it. Do you know any way to quickly check the result?

I didn't realize that the original idea was to keep such addresses so I will focus on other activities. Thanks for letting me know.

Hi, I usually only delete addresses with removed:ref:RS:kucni_broj where there are no visible buildings (it means they were demolished years ago or never even existed). Do you think this is wrong?

You may be right, this address exists in the cadaster but point is a bit behind a building:
44.808609, 20.479853
If you have seen the sign on the building it means the location in the cadaster is wrong.

Nicely done.
But this small building probably shouldn't have "inner triangles" and can be simplified to only 4 angles
