For the most part I like it, but there's a performance issue that actually affects usability. The first time you start a lesson, the editor is really snappy, but with each successive lesson, the scroll speed gets slightly slower, and a few lessons in, the entered text is just a blur, and you can't even see a cursor. This means that when you make a mistake, it's hard to tell how far you've backspaced, and I ended up bogged down in error correction loops.

I don't have anything more specific to add than that it seems to get worse over time.

Otherwise, awesome idea!

Thanks for pointing this out. I will see if I'm holding on to references to finished lessons for too long.
