The card browser has two colums named “Note modified” and “Card modified”. It is not entirely obvious what the difference between these two are. The manual doesn’t contain these names, but I think it refers to the two columns by their old names: “Edited” and “Changed”.
As far as I can see, the first one is when the note (i.e. the contents) were last modified, whereas the latter is the date when the individual card was last reviewed. Wouldn’t “Last Review” be a better name than “Card modified”?
