I just downloaded and installed Thunderbird 115.2.1. I used to be able to move the section where I saw the message to where I could see only a few email titles and the rest of the screen was the email itself. In this new version, I can only move the section where I read my email up to about half of my screen, which makes it really hard for me to see my email. Is there any way to move that section up more? If not, could I please suggest that this be possible in the next version?
