I have many many messages.
When I go to view Messages (whether Active or Archived), at first I see just the first ~4 screenfuls of message threads, showing just the header and the last message in each thread. I can keep pressing the Page Down key to see all threads (the “infinite scroll” feature).
However, if I click on a message to view the full thread, when I Cancel or click “X” to return to the message list, I am back to seeing just the first 4 screenfuls. I have to press Page Down repeatedly to get back to where I was in the thread list.
I would like my view of threads to not change after I have viewed a thread's details.
