This tab of the Configure dialog specifies the general parameters
controlling message reception and logging.
The options that can be changed here are:
The maximum age of messages that will be seen in the GUI, and how long messages
will be kept in memory.
Anything older than the specified viewing time interval (relative to current
time) will be hidden on the map or grayed out in the sniffer window. Any messages older than
the retention limit will be deleted from memory.
