When making a text box auto-sized, it would be good to set how much it expands by, be it 0.5mm, 1mm etc. I use it for laying out org charts, and to set the spacing between each box it helps when they are sized to be even 1mm sizes and sit at y value of an even number. If the box ends up auto-sized to 23.34mm then starting the next box at a y value of 25mm means a 1.66mm space between the two boxes instead of a nice even 2mm or something. If I could set it so that if a box needs to expand it does so in even 1mm increments this would mean nice, regularly-sized text boxes.
