Would also like the colors of the forms to be customizable. Like a skin, force default colors of texts so I can read them, other than what people think looks good.
A little tip I've used: If you can't read the text (dark blue text on a black background doesn't work with eyes as old as mine) highlight the text by dragging your mouse cursor across it while holding down the left button. Works for me.
