Upgrading to 1.4.2 From a Previous Version:

Opening A Connection To The Local Server:
-Shift-L opens a connection to the local server, and will launch the server if it isn't already running.

-O opens a connection to a remote machine, simply enter the hostname or ip address of the remote machine.  Currently, you will not be informed if the attempt to connect to a remote machine fails.
  
The Preference Window:
Accessible through the Application menu.

The "Connections" Tab:
From here you can control:
Which remote servers are connected to at launch.
Whether or not the local server is connected to.
The "Host" name for the local connection.  The default is "Local Mach IPC Session", and this can be changed here.

By default, when a new session is created, the new session will use the global settings and track changes in the global settings.  Each session can be configured individually in which cases it will copy the global sessions and use those as the defaults, and maintain it's own settings individually.

The "Statistics" Tab:
This is where the user can choose which statistics are displayed in the session window.
Sometimes, after AquaMon is updated, it will be necessary to hit the "Reset Labels" button.  This generally indicates that the AquaMon has new statistics to offer and the client needs to update it's knowledge of said statistics.

From here you can:
Stop and Start the server. -Shift-L starts -Shift-S shuts down.

The Session Info Panel (-I):
The session info panel allows you to set appearance settings on a per session basis.
