If you are modifying a detail trigger for a field in the IDF, and you switch to a field which does not have any code in any of the triggers, the IDF changes the focus to the first trigger in the list. If you have code in the detail trigger, it will remain focused on the same trigger, which is fantastic. However - if none of the triggers have code in them, it does not remember which trigger you are modifying. Whilst not a huge issue, it is a pain when copying code from one field trigger to a different field into the same trigger.
When switching fields in the IDF, keep the focus on the same trigger when the trigger code is blank. It stays on the same trigger when you have code - just not when it is empty.
This will make the IDF easier to use, and make the behaviour consistent for triggers which have code and ones which do not
