In order to get a better overview in the Timeline control, it would be helpful to be able to configure the Timeline to collapse email conversation threads similar to how it is done in Outlook.

I.e. default show the latest email in the conversation, with the possibility to expand instead of showing all the emails in the thread.

Collapsed:

> {Email subject} {latest created on date}

Expanded

v {Email subject} {latest created on date}

{latest email in thread}

{... earlier emails in thread}

{first email in thread}

Instead of how it looks in timeline today when choosing to show emails as conversations

| |atest email in thread}

| ... earlier emails in thread

| first email in thread
