Two things I seem to have lost

  1. I don’t seem to have a scroll bar in my folder list when I go to move a message (and I have a lot of folders)

  2. I don’t seem to be able to get the message list to just one line (even if subject is very truncated)

  1. That’s a bug. I created an issue here: Add scrollbar to "Choose Folder" screen · Issue #5438 · k9mail/k-9 · GitHub
  2. That feature has been removed.

On #2 that’s a shame.

I also no longer see the number of unread messages on the top.
