As implicit in using your flashcards, I think they are great.
May I ask for an improvement in the example section? It would be great to see the source code of the different examples, so I can easier work with them. Reverse engineering is so cumbersome ;).

Even for your ONE example, I need to figure out the style myself. Your work IS great, your documentation isn’t. But in adoption of tech, documentation is a big factor. And from a creators perspective, everything is known, everything is straight forward - if it wasn’t the creator wouldn’t have done it this way. Implicit knowledge is the keyword here.
Talking specifically of your extensions: not being documented at least in a intermediate manner, it hurts your great results. The best tool won’t be used if only few people are able to understand how it works and have to be used.
