Thunderbird layout: can we have the email view at the center of the screen?

Cross-pot from Thunderbird: https://lemmy.world/post/1637657

It seems to me like that this is the most efficient way to read mails: to actually have the mails at the center of the screen in vertical view, not at any side, bottom or top.

Either option is fine with me:

1. Folders | e-mail | Inbox
2. Inbox | e-mail | Folders
