It's been a year since the removal of Divider Lines, which led to difficulty reading for people with myopia/astigmatism.

Divider Lines were simple grey lines similar to the current red lines indicating new messages that appeared between message groups. They were removed in a UI Update last year, and it caused issues for people with myopia/astigmatism.

I don't have myopia/astigmatism, but I can agree with them on the whole thing. Divider Lines were a simple and clean way to nicely separate message groups from each other, and it made reading things much easier.

Just adding them back in as an accessibility option would make a world of difference.
