Ahrefs also offers -what they call- 'position tracker data', with other words: keyword rankings. It would be very nice if that data would be accessible via the ahrefs-connector in seotools for excel. Which doesn't seem to be the case right now, The only other way to get rankings (as far as i can see) is via the SEOlytics-connector, but that tool is extremly expensive.
Yes that hasn't been integrated.
Please create an idea for this on http://seotools.uservoice.com/forums/134457-seotools. If it get's enough votes it will be built for a future release.
