I have been playing around a bit and noticed that no matter what the drawer bottom is the same thickness as the sides in the menu for “Drawer box material” It would really be nice to specify a different material for the bottom of the drawers. If I make my drawers from 1/2" or 5/8" I usually use 1/4" bottoms and on lighter things maybe 3/16" Even on the heaviest of duty, typically a 3/8" drawer bottom is plenty even if the sides are 5/8"
