Let’s say you have one application that you’d like to follow you to every space you have. There is a very simple way to make this happen.

1. Open System Preferences
2. Click on Expose & Spaces
3. Add the Application that you’d like to assign.
4. Instead of choosing a specific space, just choose “Every Space”

That’s it, it’s that simple. I know it isn’t a difficult or time consuming item, but if you’re looking for a way to keep all of your chats going with you in every space, it’s a very useful tip.
