Hello! An upgrade as been made and the interface is getting once more worse and worse: simply LACK OF SPACE that LEAVE NO PLACE FOR EMAILS! Thunderbird version is 115.3.1 Here is a snapshot that shows: − a useless "status" bar '''without folder total/unread numbers''', − menu bar and toolbar inverted, − a huge list of message that '''cannot be reduced below 8 lines'''; why the hell someone as added this limit that didn't exist before!? We could reduce to one line if we want or… punctually need it. − a '''TOTALLY useless message list header''' (name on folder panel, size in status bar, filter in upper toolbar − a NOT CONFIGURABLE message header, especially, impossible to '''choose the kind of button''' (text or icon, to get PLACE) in the action bar… that starts with a SPACE! Neither can we choose which buttons to move in the drop down list "plus". Actually, the message list header was used to display such actions. This would free space. − a useless empty space above the account panel; it would be much better to get back the receive All/this account button on top. − finally, the whole aim of a mail software is to… READ EMAIL… in '''a space as large as the private life warning banner!''' This is just nonsense, unacceptable. It started years ago for some of these designs, but now it is the worse I have ever seen; it makes thunderbird simply unusable. The settings panel doesn't help, with so few parameters. The whole thing being designed for a 30" screen I would be please Thunderbird ships me and buy me, with the trolley to carry it with my laptop. As a Linux user, I am not working on full screen windows style, but reduced size to work on and access several windows at a glance. ''Working full screen is NOT an option.'' By the way, the 99% active surface of the windows makes it bloody hard to select below another one or simply… MOVE! Especially since there is no more title bar… (I just have found the '''ONE squared cm''' that allows it, with no menu bar…) So, how can I set back old disposition or how can I set it in a pleasant and usable way? Especially these two points: − '''reduce the message list''' to less than 8 or 6, − set the '''message header buttons''' to icon OR text. Sorry for the tone, I am really upset to see this evolution for a few years imposed to me, a user since the beginning, when it was in the Netscape suite. I am wondering what tiny laptop users think of it. Thanks.
