I’ve been using several Labs apps for quite a while, but there are some more additions that are worth noting, so I decided to do a run-down of the ones I use. There are quite a few more out there that I don’t use that are particularly handy to people, depending on the content of the mail you receive, but just not for me.

1. Signature tweaks by Keith C and Dave C
   Places your signature before the quoted text in a reply, and removes the “–” line that appears before signatures.
2. Right-side chat by Emily C
   Move the chat box to the right side of the inbox.
3. Right-side labels by Emily C
   Move the labels box to the right side of the inbox.
4. Forgotten Attachment Detector by Jonathan K
   Prevents you from accidentally sending messages without the relevant attachments. Prompts you if you mention attaching a file, but forgot to do so.
5. Mark as Read Button by Mark K
   Tired of spending all that effort to click on the more actions menu every time you want to mark messages as read without reading them? Now just enable this lab and that is just a button click away!
6. Title Tweaks by Fedor K
   Changes order of elements in the browser title bar from “Gmail – Inbox (20) – YourEmail@gmail.com” to “Inbox (20) – YourEmail@gmail.com – Gmail”. This way you are able (most of the time) to see if a new mail has arrived even if Gmail window is minimized.
7. Inserting images by Kent T
   Allows you to insert images into a message body. You can upload and insert image files in your computer, or insert images by URLs.
