Thanks for the great feedback, I’ll try to cover it all:

The mobile design: I absolutely agree, I didn’t expect so many of our users to come from mobile as the target demographic is desktop developers. I see now that I may have misjudged things a bit. Future plans definitely include a nicer website with better mobile support.

Header: They won’t very soon, Pakkly’s still in Beta, some things are placeholders for future functionality.

The Steps section: Absolutely agreed, we are already working on a video explainer.

The Newsletter section: I thought it fitting into 100% of the viewport height made it distinct.

In regard to caching, we had a caching plugin but it caused some strange layout bugs so we disabled it, I’ll look into those, thanks!
