You can easily access your Gmail Labs by heading to the upper right hand corner of your inbox. There's a drop down menu there.
Right Side Chat
It's often more convenient to have your chat box over on the right, where there is more space for you to work off of.
Signature Tweaks
This removes the "--" line that appears before signatures which is a nice little added touch that looks quite nice.
Sender Time Zone
If you work with a lot of folks who are international, you know how difficult it is to wrap your mind around all those hours.Video chat enhancements
Everything's bigger and better with this one:
Pictures in chat
You can see photos of the people you're chatting with if you use this one. That is, if they have photos uploaded of course.
Message translation
This Lab offers simple integration with Google Translate. Very helpful for dealing with language barrier issues.
Inserting Images
Instead of just attaching and image, you can insert it into an email - which can be a whole lot easier.
Green Robot!
You'll see the green robot when someone is available in chat but is on their Android phone.Google Voice Player in mail
Want to listen to your Google Voice messages right inside your email? This is the right Lab to be doing that.
Google Docs previews in mail
Any Google Doc link is instantly recognized resulting in a small preview window right inside of the message.
Create a Document
You can launch that great idea in the form of a Document right away with this Lab turned on.
Undo Send
This one is fantastic: you'll get a short window after you hit send to make a quick undo and recheck your email.Of course, we certainly encourage you to take the time to experiment with some of the other Labs that might be useful for your domain. In fact, post in the comments if you find something really useful for all those Google Apps users out there that we did not include!
