Transparent Overlay Message Box API (in addition to status bar API)
Explained here: http://www.azarask.in/blog/post/monolog_boxes_and_transparent_message
It’s simply a large and translucent message that’s displayed over the contents of your screen. They fade away when the user takes any action (like typing or moving the mouse). In practice, the message is both noticeable yet unobtrusive. And because the message is transparent, you can see what’s beneath

It would be interesting to have support for something like this built into Sublime Text. Failing that, there are ways you can approximate such behavior. For example, on OS X you could write a plugin interfacing with Growl for the overlay feature.
