Dashboard-like view of all new notifications from all applications. Is there such an application?

That is a wonderful idea, although I would like one for Windows. It’d be great to see all my activity updates from a ton of websites that I’m registered to. Like Fluther, Facebook, Hunch, Urbanspoon, Gmail, Google Reader, etc.. etc..

So if anyone has an idea that would work on Windows as well, that’d be great!

Have you tried Growl? It does various heads-up notifications, which can be “sticky” or not. It works with a wide variety of OS X applications, 3rd party, etc.

i’ve used it for years and i love it. when i get a new Mac, it’s one of the first things i install.

fyi: it works with skype, adium, Mail, Thunderbird, Facebook, iTunes etc.

For twitter, i use Tweetie, which puts a nice icon that “lights up” on the menu bar up top – i believe it will ding too, if you want that (which i don’t).

as regards Facebook i don’t have a notifier for that.

I have growl. O don’t know about enabling it for individual apps apps I just know that aloet of others apps use it by default. I will look more into it. Is there a way to see a history of growl notifications? Sometimes I ignore them and I missnout on what thy were telling me. Lol
