Event Detail Trend Time Buffer
Ability to set a default lookback and look forward period on event detail trend. if the event is 30 minutes long and my lookback and lookfoward period is 30 minutes then the trend timeline would be [event start time]-30m to [event end time]+30m. This gives the user context to what happened leading up to the event and after the event in the trend.

I disagree - as sometimes, the ONLY thing I care about is the root cause. Maybe your suggestion should be that we need one or the other, or both? Right now, you get the event, or both. I would love a shot to just get the root cause events.
In response to Roger Palmen, "I currently use Custom symbols that take..."
Thinking even further, we currently have absolute time, and relative time in PI. Relative time is than related to a fixed point in time (like *, y, t, etc.).
Ideally we could have a time relative to the EventFrame start and end: Event.Start-10s to place on the timebar... this splits the functionality into two parts where the first part allows to place an EventFrame in the timecontext of a display (and not just the timerange).

This is indeed something that I miss as well.
The option to have a rootcause event is not convenient, because of the double amount of Event Frames that will be generated by this. For scaleablity sake, it is not the solution that we are looking for.
I currently use Custom symbols that take an Event (e.g a batch), determine chart start- and end-times from the batch start- and end-times (+/- several minutes), and plot a chart based on those times. But that's quite a big piece of custom code. I think showing just a small percentage before and after should not be a major deal to implement.

agreed - I do this with the hyperlink function in excel - will pull a bunch of events in and let the user build the before/after offsets so that they can see before the event started and after the event ended. It would be nice to have some native functionality like this.
Currently when i visualize and EventFrame in PI Vision, the trend does not show the exact 'change' that leads to starting or ending the EventFrame, as the exact start and end times are used.
To properly see the 'change' that led to the EventFrame i want to see just some small time before and after the EventFrame.
As events can differ between seconds and hours, this would ideally be a percentage.
