描述

Hey,

I noticed there doesn't seem to be any kind of autoscroll feature when inserting new text with par.Text += "Text\n" and it is at the bottom. It would be nice to have this boolean available.

Also, it doesn't seem to be possible to not wrap text inside the par (when using the layout at least). Meaning, text will wrap as you decrease the width. This works fine with lists though.

Thanks

研究方向
Investigate the Paragraph widget implementation in termui, likely in elements/par.go. Look at how text is appended (Text +=) and how the viewport scrolls. Check if there is existing scroll functionality for other widgets like List. Consider adding a bool field like 'AutoScroll' and update the rendering logic to scroll to bottom after append. Also review the layout system to understand text wrapping behavior mentioned.
