We have almost the same nickname!

Yeah great idea! I dont think that I saw such issue in github, but I would also like to see this feature.

Yes, you have to read the OP to mark it as read. After read, with new comments, post will remain as read. There is no way for that at the moment, but I think this is great idea!

Sadly no, does not seems like it :/ But implementation of this is already being discussed at https://github.com/LemmyNet/lemmy-ui/issues/384

There is a setting that you can disable “Show Read Posts”. This way you will only see new things :)

Trackmania 2020 is great!
