Vertical Dividers and Text Boxes

I use the horizontal divider with a solid line to break up the sections, it is very convenient! It would be nice if the vertical divider also had a solid line and the dimensions could be changed (like the horizontal divider). 

Another suggestion would be to have the option to put a solid box around the text boxes. The layout with two text boxes: each text box would have a solid box around it to separate the two boxes.
