Serato users have had spectral colored waveform displays for who knows how long and can certify that this is a good and useful feature.

Here is a link to NI forums with a user asking for this feature and getting trolled by a mod: https://www.native-instruments.com/foru ... hp?t=77200
Come on. "Missing something in Serato is not a good reason to want it in Traktor." Really?
To the best of my knowledge, Serato does NOT have beatgrids. This is a really huge feature. You can make a very professional mix in Traktor with just a mouse if you know how. To those who don't know what I'm talking about, I point you here: http://www.youtube.com/watch?v=pAW8X9RSt7A Big Shout Out to Ean Golden. However, if you want to beatmatch tracks that you haven't made a grid for, you have to find a snare.. If you're recording your mix (or shoutcasting), as I said with no timecodes and no cueing, you aren't gonna want to use your ears. If you can see that a snare is white, there's no chance that you're gonna fuck up. This is exactly why I want this simple feature that someone else asked for a year ago. So what the fuck?
