When reading messages on PC, if a bottom level message to a thread gets a response it shows with the green border and all, but any response to that response shows on the same level and same color as the one it is a response for, so it seems they both are responses to the bottom level message.
This makes it very difficult to make sense what message they are responding to. On the mobile browser it shows correctly with different colors and more levels than 2, so I don’t understand why it’s not working on PC.
I’m not quite sure it’s documented anywhere exactly, just had a search and didn’t find anything yet, but I can imagine the different views work better for microblogging. For instance, I think chat view appears to be how mastodon/twitter would display replies. Classic sort of seems like an inbetween where you still get a different level off of the first reply but it goes into chat after that. Since you might be looking at things like mastodon toots, maybe the idea was to make a way for it to be viewed similar as well
Edit: I guess classic is sort of like youtube comment section now that I think of it. Though it might be better if comments were collapsible
