IMHO the hyperlink behind 'Last change' should not point only to event details for unhidden events. It should do it on trigger level as well.
That would allow to reach event details of a trigger's recent event very easily.
Now one has:
- either to make sure events are not hidden (on precondition the last event is not older than configured by 'Show events not older than (days)'
- or to visit events via the trigger menu, then select a proper time period and finally use the 'Last change' hyperlink there
