Description from store
This is an extension that marks new posts with a vertical new line at the left edge of the new post.
The new post is marked as new at all subsequent post times starting from the last new post time, and the new post is marked as new at all subsequent post times, even if it is a repost.
The new post time is retrieved from the followings in the home page.
It is updated by long pressing the middle mouse button (two-point touch) in the post field.
