Currently in the problems widget it's not possible to show more than 100 lines/problems. This is limiting the useage of the dashboard as a workspace for NOC and other servicedesk like engineers.

For example, if there's a high number of alerts coming in from telecom equipment, hundreds of alerts aren't that weird and parsing through them is done regularly. 

The problems page has pagination and allows more than 100 lines per page. The problem with the problems page is that we cannot create filters and set them for entire groups of people. The other problem is that we cannot show related information from other parts on this page.

As such, 100 problems is not enough. Proposed quick solution, change the follow line:

define('ZBX_MAX_WIDGET_LINES', 100);

to

define('ZBX_MAX_WIDGET_LINES', 1000);

in /usr/share/zabbix/include/defines.inc.php 

Proposed long solution: Introduce pagination on the problems widget.
