Last night I was sharing a FaceTime session with my wife via my MacBook Pro. In addition, I was also looking up some information in a Web browser. Several times I was annoyed that the FaceTime window kept falling behind other open program windows.
FaceTime (version 1.1.1) for Mac doesn’t appear to have an option to keep the windows on top. I’m not sure if this was an intentional UI decision or just an oversight – chat programs often have this capability. It’s probably something that will be added in the future but until then I found a solution by installing a program that I’ve used in the past.
Afloat works as an add-on that provides a handful of new window controls, including the ability to keep a window on top for programs that do not have this option built-in. The program is free and the current version works in Snow Leopard and Lion. It works directly from Window menu item. It doesn’t support every program (I didn’t see it appear in Firefox, but it did show up in Acrobat Pro and FaceTime).
