Was checking my e-mails and found that GMail has recently updated the UI.. Just before 6-7 minutes I checked at that time, I was not getting change.. and right now, getting changes in the UI..
Some of the snapshots are here,
Instead of all the options, menu has been given now.
Reply and forward, something is changed here !!!
According to new features mentioned on google site !!..
Reply on top
No more scrolling to the bottom of a long message to find the “Reply” link. Now there's a Reply button right on top, along with a lot of other options under the little dropdown arrow.
Embarassment-reducing new message notifications
Ever replied to a message only to find out that someone sent a better, smarter reply right before you? Now, if someone sends a reply while you're in the middle of reading a conversation (or replying to it), you'll get a notification that a new message has arrived. Click "update conversation" to see what you’ve missed.
When viewing a conversation, use the new “Forward all” link on the right if you want to forward the entire conversation instead of just one message.
Chat even when your friends are offline
Chatting in Gmail just keeps getting better. Now, if you're chatting with a friend who goes offline, your friend will be able to see whatever you were typing the next time he or she goes online.
