If you press Q you can square buildings to have nice right angles.
Can also right click and do it from the context menu.

Useful changeset comments please

Also the blablabla leaked into this path

fixed it up in changeset/178154515

leisure=pitch on the whole building isnt right, a node with club=sport would be better.

Actually now im wondering how old this data is. Im local to node/13518303211/ and im pretty sure that hasnt been there for quite a while.

Most likely maps.me confusing OSM edits with personal bookmarks.
Looking through the edits it looks like theres good data, just needs to be turned into something usable.

Theres still some weirdness with relations here.

"building:levels=1t"

Quite a few of those kindergardens were already on the map, please double check before adding duplicate points.

You should make circular things circular. In iD the hotkey for that is O.

"sport=soccer;w;darts"

Zīmējot ēkas būtu labi piespiest Q lai būtu smuki taisnstūri ar taisniem leņķiem.

Also only changing road classifcation partially. I mostly agree with the changes but it doesnt make sense if you only do half a road.

You can edit more than one road per changeset. No need to constantly upload small edits.

Vārti uz galvenās ielas? Laikam iD automātiski "izlabojis" nedrīkst tam akli ticēt.

Why do you map parking spaces like this? Its insanely inefficient and inaccurate. JOSM has a terracer tool thats perfect for it.

You only changed part of V301 to tertiary, maybe the rest should be changed too?

Please check the data before adding duplicates. Also names shouldnt be descriptive, theres no need for "name=kindergarten" if it has "amenity=kindergarden".

When making areas like this one
way/1452682582
you should connect the paths across it, most routing engines cant do anything with areas.
