If you are a fan of Gtalk or Gmail Chat, then you are probably aware of the multitasking with all the Gmail users which continually pop up to say hello. In order to reduce the need to open up new windows if friends send you a cool video to watch from YouTube or Google Video, the new Gmail chat video preview is available.
This is just another great tool for Gmail chat that is extremely useful and saves you the extra few seconds or headache of the need to open the video in a new tab. To watch a video preview, simply click the video preview button and viola…a miniature version is already right in front of you.
By the way, this is currently for YouTube and Google Videos only.
