This solution was tested only on zabbix 2.0
Description

This hack allows you to view events for each severity category separated in 2 rows: unack and ack.
So you can see at a glance what events are new and must be resolved and what events are old and have been already acknowledged.

Usage
Download the php file and overwrite the existing one in /var/www/html/includes (make a backup first).
Configure the dashboard filter with "Problem display": sepparated.
Alternatively, you can replace only the function "make_system_status" in your file.
