In old style of Gmail, a conversation (grouped messages) is displayed using different color for different recipients/senders.
With the new appearance, that has been removed. This gives me find quite a lot of difficulties when mailing with multiple users at the same time.
The new interface put in the photo of the sender for each message. But that is not very useful for me when I look back my messages to seek for the ones that has recipient to be Ms ABC for example. With the old interface, I just look for the color; now, I have to read wrong-designed
If you know how to turn this on back, please share.
The New (the different color rectangles should be color by Gmail)
