UE 4 Gems documentation page

I’d like to see a page in the UE 4 documentation that’s something akin to this page from the UDK section of UDN. I know that we already have these cool sample projects in the Marketplace and whole host of video tutorials on the youtube channel, but I would really like to see a collection of these sort of intermediate and higher level things with full explanations and documentation. I’m not sure about the rest of you, but for me staring at a bunch of blueprint nodes really only teaches me so much, and usually pretty slowly, whereas the written documentation has always seemed much more handy as a quick reference for how something was done or reminding me of exactly how something works.
