I found that the ‘Saved!’ message sometimes a bit confusing. After saving the entry you’ll get the message, but having multiple tabs open with multiple Saved! messages makes it a bit confusing, so I added a bit of code, that removes the message after 10 seconds.
In you extentions, add after line 175 the following code:
$msg .= '
< script type="text/javascript">
$(document).ready(function() {
$("#message-publish-tweeks")
.animate({opacity: 1.0}, 10000)
.hide(2000, function() {
$(this).remove();
});
});
</ script>';
(remove the two spaced in the script tags 
)
