1. Removing functionality to flag the message as a spam from the right hand side of the msg - next to the delete button.

2. Being able to list/sort all messages by a specific sender by clicking on their email address.  

3. Now I find out that you can't sort messages by sender by clicking on the sender column.

These functionalites were extremely helpful in time savings and now they have been removed. 

At this pace I will have to abandon Zoho for Google or another provider.  One of the reasons I chose Zoho was the integration, ease of use and functionality!

Bring these functions back.
