Hopefully this can be also integrated in rank tracker.

Thanks, this looks interesting, we will analyze it and see if something like that can be added.

Cool, another feature I would like is to be able to export the color markers you can set for different keywords in rank tracker so you can show your client what the interesting keywords are.
