I now found some time to have a look at the patch. Good job! However, I 
think the approach is not quite in line with what I had in mind when 
initially introducing the flash messages.

Steffen's flash messages at the top of the TYPO3 backend are a great 
tool, but they must be used carefully I'd say as they are rather 
notifications I'd say.

So what I had in mind again: We know the flash messages above TCEforms 
f.e. which tell us about a successful or failed operation. For these I 
wanted to have the positive ones ("OK") fade out.

For your case which create the fading messages at the TYPO3 backend's 
top, I'd rather suggest to extend t3lib_FlashMessage as 
t3lib_NotificationMessage.

I'm currently reworking the patch so that it fits with the idea of 
fading out the messages as described. I'll also fix some wording / 
naming of variables and methods along the way.

Helmut, for the issue with the messages in the install tool and other 
places I figured that this won't be a too big issue: All the relevant 
flash messages which may fade out are sent through 
t3lib_FlashMessageQueue, so this is the easiest way to tackle that 
issue, by having the queue take care of fading messages out...


All the best
Ingo
