Version 115.3.1 removed the ability to select multiple messages in my inbox and reply to all of them. Many times I have to reply to a group of my customers' separate e-mails with the same reply. Now if I select multiple e-mails the old message->reply to all is dark! Please resurrect this feature!
Also, when I change mailboxes, I have to scroll all the way down to the most recent e-mails to check them. The GUI doesn't remember where I left my place in the list anymore.
