Would be cool if TextView had an AppendText in addition to the current SetText one, which always clears the textview before rendering it again.
AppendText would be helpful for a log-tail like UI where new lines are appended to the existing text.

As shown in the TextView Example, you can use TextView as an io.Writer. This allows you to continue to append text.

fmt.Fprintf(textView, "%s ", word)
