The general structure of a report is actually painful to maintain
Dataitem
{
DatitemProperties
Columns
NestedDataitem
{
DatitemProperties
Columns
triggers
}
triggers
}
ReportTriggers
Procedures

The following structure would be much less confusing;
you can see much easier on which dataitem this trigger is attached

Dataitem
{
DatitemProperties
Trigger //Moved position
Columns (Can this be collapsed to hide
Nested Dataitems
{
DatitemProperties
Trigger
Columns (Collapsable please -so that the developer can hide the whole structure with one node)
}
}
ReportTriggers
Procedures
