I would like to have a pinnable message for errors and success message display. By default it disappears within seconds but if pinned, it remains on the page. The message should be displayed floating above the html content but the html content must be accessible. I have remembered using similar message somewhere a year ago, but could not find it to referenced it. Is there any plugin for that, or any reference to start working on?
Further to gral.pancho.villa's capable answer above, here is another jQuery plugin that could be helpful.
The operative search term for this one is "Growl", which is a notification system used on Mac and Linux (and now Windows) OS.

Other references of debatable interest:
What about Sticky Notes? It is a jquery plug-in, and a base that you can start with. You know, it was not hard to find. I guess that is why the Question got a couple of downvotes. Anyhow, the Key Words for this search were: "Sticky", "Note".
