Sometimes it's very easy to set a trigger where an error is detected in firmware. However, what has happened just before the error is usually what you need to know for debugging! It would be very nice if I can say "trigger on X, and show the waves starting from Y seconds (or milliseconds) before X happened."

It would be grateful if the trigger occured and then measurements stops.
The presetted time will be shown as history from the past to the trigger.
So it will not be neccessary to hit the stop button.

It is already possible:
Go to "Options -> Preferences -> Capture" and set the "Pre-trigger buffer size" to a value like X-Y (e.g. = 5 seconds) in your example. Than you trigger at point X and can see the wave 5 seconds in front of trigger point X. It is independent from the "Duration (Recorde data for)" .... seconds.
