Thunderbird 128 feedback "no message found"

[shoi]

Recently when I first launch TB (so open Inbox) I see the incredibly alarming "no message found", then a second later the mailbox fills

It displays too soon.  I have become inured to it, but the jump in my blood pressure for the first few days was dangerous.

I agree -- display some sort of "working..." message until it has been determined that there was "no message found".

May I suggest that the message "No message found" is changed to "Checking for messages..." until the checking is finished. Although the status line at the bottom shows that checking is in progress, the "No message found" is misleading.

Similarly, maybe when there are messages (the most common case), add some pacifier while checking the server. For example, change the mouse cursor or show a rotating circle or a message "Checking...".
