Hey there!
I hope this okay to post this here, I have just launched my website and hosted some of my existing tutorials on Tools Development,
Extending the Editor with C++ and Slate, and Technical Art.
I created this website with the intent to collect all resources I find on extending Unreal Engine,
developing tools on Slate and C++, and hoping to make creating editor tools much more accessible to the larger Unreal Engine community.

I will have more tutorials both written and on YouTube coming soon,
