Yeah, I guessed that that's something you are against 😅 I just get annoyed when I scroll the wall all the way to "last seen" and then forget to switch to do the same on the other wall.
I have a limited list of 13 people or so that I actually read (using listr) and so there it would be cooler to just have a single wall. The 13 people bring enough of novel and disjoint content, so that's quite sweet experience for me.
