Allow the rectangle textbox to grow or shrink based on the text within the box. When creating data driven pages, I sometimes add long text to describe the data in the map. If I size the textbox for the longest text and the text shrinks for one of the maps, I'm left with a large blank space between the bottom of the text and the bottom border of the box.
Also, within a rectangle textbox, allow me to control the vertical justification of the text. Currently, it's only top justified. I'd like the ability to make it center or bottom justifiy.
