Now in Monitoring-Triggers there are 2 columns with effectively the same data: "Last Change" and "Age".

Replacing "Last Change" with "Last Check" column would make this table much more informative - you'll see not just trigger statuses but also how current they are.
In Nagios/Icinga this view is called 'Service Status Details' (see attachment).
I think it's very convenient when something goes wrong on a host and you need to evaluate the situation.

And also it would be great not to reset automatically 'Triggers status' to 'Recent problems' in filter settings, but let it stay in the last selected state (like 'Minimum trigger severity').
