[TYPO3-core] RFC #16318: Enable FlashMessages to fade out after delay

[Steffen Gebert]

Hi Ingo,

Without the parameter {remove: true}, the space appears white - with the 
parameter, the content jumps. Other possibilities?

>> Another thing: Adding this functionality to the FlashMessageQueue

Okay, I agree that this is not a solution^^
However I dislike different behavior for the same thing, saying 
"everything went fine".

Yes, but for FlashMessage, which don't have to survive a request, we 
shouldn't always (have to) use the queue, don't we?

No, searched for it, found nothing. I think it's "because we can" :)

Kind regards
