I would like to be able to click, drag, select, and move multiple Free Text boxes at once.

Separate request likely, but it would be great if text boxes had some sort of alignment feature so you could snap align text boxes with cards or other text boxes if use chose to. Alternately, give the user a perspective (dashed line) of where that text box is in relation to cards or text boxes next to (horizontal) or beneath (vertical) it.
