Hi, I want to show the default output to output widget. When the content gets updated, there is a way to add a scrollbar. But when there are lot of lines, I want to make sure the scroll bar goes to the end. Right now, the scroll bar doesn't move down, we should manually go down to look the output. This addition would help us to see that output is getting updated. Any suggestions are welcome. Thank you.
