Let’s say you’re working in a power-crunching app like Photoshop, and you go to apply a filter to a high-res image, and it’s going to take a minute or two to process your command. You’re going to get a progress bar so you can see how long the process is going to take, right?
Well, thanks to Mac OS X’s way-cool Dock, you can switch out of Photoshop to work on something else and the Dock will let you know when the filter is applied. How? Well, when a progress bar appears in Photoshop, the Dock automatically adds a tiny little progress bar to the bottom of the Photoshop icon in the Dock so you can keep an eye on the progress, even when you’re doing something else (like checking your mail, shopping online, or writing a letter).=
