PDF form fields have a dialog box that allows you to enter specific size and location parameters. Text boxes should have the same functionality. Dragging text boxes around and eyeballing the alignment is unacceptable. I need to be able to type in the exact distance from the top (or bottom), and left side, as well as the exact height and width of the text box. This is in line with every other GUI form tool I've used since 1996. I don't expect Acrobat to be a full composition program, but precision placement of text isn't too much to ask.
