Why no colored wave?

Just wondered - after checking the usb containing the export of my RB library, I noticed, that the waveform of each track is being exported as an image and so the cdj/xdj just reads and displays the image... 

Why the waveform is not being exported as spectrum if the colored wave is choosed as the default option in the rekordbox? - technically there is no difference - its just a few lines of your code that needs to be changed to make a huuuge change to all the users...

thanks!
