Development suggestion - for search:

It would be nice to be able to click on sender’s name, right in the messages panel and get displayed all the messages from that sender in the panel. 
Currently the one click brings the message up on right side, two clicks open the message.
My suggestion is to split the message field horizontally. Double click on sender would display all the messages from that sender. Double click on subject would open the message.
You could also consider a double click on date to reverse (toggle) the time order of messages.

Hello Peter,

Thank you for getting in touch with us, I’m however not completely sure what you mean, could you please elaborate? What is available now is the Contact Detail section of the Sidebar on the right side. When you open a message from a specific sender, you can see the complete history of conversation with that sender in the Contact Details. For complete description of the sidebar and its options please see []( Started/Sidebar.htm “Link: Started/Sidebar.htm”)
