What's more annoying "Saving message..." or "Message saved to Drafts" message? Both?

I wouldn't like to create an option for this, but maybe we can make it less annoying.

From the wording of his message it was the distraction of the message popping up that he disliked.

Thunderbird saves drafts as you type, but does not flash a message everytime it saves... same for editors such as libreoffice. He only complained after I increased the save frequency.

(previously he complained about losing the mail he had typed, which is why I increased the save frequency)

I got an idea, you could make it flash the message the first time it does it, and the message could say:

"Saving to Drafts, every X minutes"

Then after the message is displayed once, preferably don't show it again, or at the very least show it at less frequent intervals.

I wouldn't like to create an option for this, but maybe we can make it less annoying.

Maybe an idea to improve the situation without adding an option would be to define a period (say 5min) under which saving messages would only be displayed once, whatever the saving frequency.
