Thank you very much for the article, I'm really enjoying it. I have a few comments:

- When hovering over some notes I see the citations perfectly, but when there is math involved like for example the one about spectral decay the math is not rendered (I'm using Ubuntu, I have tested both in Firefox and Chrome).

- I see you can open issues on github to send corrections. I wonder if there are other channels of communication also to, for example, address problems like the previous one and also to discuss the article.

- I see people like a lot the figures. I think too they are great but what I really love is the writing and the math exposition.

- I think that a default animation for the figures, if they are meant to be manipulated, would be great.

I will say it again: great article. I have bookmarked the journal and I will proceed to read everything published which looks very promising too.
