Yeh, it took 2 years but i'm finally getting started:

Basically I made a system where a coding tutorial lets you pause and edit the code in the video. It's also like scratch.mit.edu where anyone can share a simple mini-game or program they coded. Aaand (the feature khan academy does not have) anyone can record a "edit code in the video" tutorial through a live editor I built.

here is a link to the thingy https://sparker.gg/codecasts/d4bd40f9-d5cb-49a0-b92f-b5da73d20952
