This screencap illustrates the problem with the right navbar. I'm harvesting memes in memes bread and a lot of the posts are mine – but not nearly all of them. In this cap there are 67 UIDs in the memes bread out of 312 posts. And the post I'm currently looking at is one of a series of 10 in a row made by somebody other than me. But look the right nav bar. There's no indication that there are any posts made by anybody else. It becomes useless.
The old JS

formatted the nav bar as an accurate representation, with relative sizes and positions of posts depicted accurately.
