How to get the clip begin and end time?

Maybe this is an answer or a clue to your question.

Start and end trim points of clip

Is there anywhere in Shotcut that I can see the trims (start and end cuts) of a clip? Properties would be the obvious place to see this information imo. Would also be completely awesome if I could edit these within Shotcut, e.g. I see that I have trimmed the first 30 frames from the source clip, but I want to make that 20 frames instead.
