I think the Help center has a lot of usability glitches:
I would also like to suggest а very general UI frame of thought for improving it:
Another thing to suggest is for Webflow to stick to a "one best tutorial hub" policy. Currently there are several (volunteer) sites offering tutorials (none of them especially good). I think Webflow could reduce this type of noise by offering good volunteering options towards its own help center. Then anyone who would like to correct/ improve/ enhance the Webflow tutorials would be able to do so, without resorting to building his own tutorials site and increasing complexity this way.
And lastly, an interesting innovation at StackExchange: http://stackoverflow.com/tour/documentation which might spur good ideas for Webflow's Help center.
