Add a horizontal line button in the text toolbar to make separating texts more organized and look neater.
The horizontal line button would act as a <hr> tag does in html and would print a horizontal line.
You could set the dimensions of the horizontal line to your parameters or if you left the parameters blank, it would stretch across the width of the text box by default.
It would look similar to this:
__________________________________________________________________________________________________________________________________________________________________________________________
People use underscores to do this already, but you get space above the horizontal line where as if an <hr> tag is implemented, there would be no space on top.
Space On Top
_________________
_________________
No Space On Bottom
<hr> tag would have no space on top or bottom.
