Now when we are living age of AI translations I’m fixing a lot typos and for AI really difficult structures. Hopefully I’m not stepping on anybodys toes, but I would guess the situation would be similar than if out there is a Scots speaking forum 
(meaning, there is around zillion way to spell a word).
Notifications bothered users a bit because they felt I was fixing meaningless typos — as I did in deed. Well, then I stopped that when I realize that I don’t have any way AFAIK to force re-translate. But my point is that from my point of view there shouldn’t be notifications — unless like some percentage of a text is changed or amount of charachters.
