Option for "Return to the room previously opened in a space"

### Your use case

#### What would you like to do?

When clicking on a space, do NOT open the last active room, or any room as a matter of fact, and stick to the space home.

#### Why would you like to do it?

To get an overview of unread messages in a space, without accidentally reading one (for which a "mark as unread" would have helped)

#### How would you like to achieve it?

### Have you considered any alternatives?

SchildiChat already implements this.
