New comments are now shown like this: 6 + 5 From the school course of arithmetic it is known that 6 + 5 = 11, but there are not 11 comments, but 6, of which 5 are new.
I propose to show the number of comments as follows: 6 (5 new). Moreover, if a person did not look at all at all, then for him all the comments will be new, and it’s necessary to show this: 6 new ones.
If a person has seen all the comments, then for him they are old, and it is necessary to show it like this: 6
