All the posts you will visit starting now will show a (new +1)...(new +2)... next to the comment icon when new comments are posted. The tag will automatically disappear when you'll open the comment thread and it will come again when new comments will be posted. We know a lot of poalrs have been waiting for that feature and it took some time and lots of coffee to get it debugged and optimized, and as usual, if you notice something funny, just let us know in the comments. (We know it doesn't fully work on endless scrolling and we'll push an update later on). Cheers! Poal Team.
