Have you ever wanted to cut and paste from an existing email while creating a new email?  I reuse my email content all the time.  Well, now thanks to Google Apps constantly updated capabilities, I can more easily compose new emails while accessing content from my previously received emails.

If you use Google Apps you may use this new feature.

Gmail's new compose and reply experience

You can now write messages in a cleaner, simpler experience that puts the focus on your message itself, not all the features around it. Here are some of the highlights:

• Fast: Compose messages right from your inbox.
• Simple: Redesigned with a clean, streamlined look.
• Powerful: Check emails as you're typing, minimize drafts for later, and even compose two messages at once.

Try it out!

Once you click the Compose button, click the "new compose experience" link right next to the Labels button at the top of the message. Until the change is fully launched, you'll be able to choose whether you use the new or current experience.

If you change your mind or if you need to use a feature that isn't available yet, you can switch back to the old experience at any time. Here's how:

1. Click Compose
2. At the bottom corner of the message pane, click the More menu icon  next to the Discard button.
3. Select "Switch back to old compose."

Details of the new compose feature may be found at this Google site
