Without meaning any offense to the OP, I think this is a pretty low bar for Emacs eye-candy... Nicolas Rougier's "Nano Emacs" [0], or his previous "Elegant Emacs" [1] are better examples. You can also get pretty far using variable-pitch mode for mixing fonts (for example in org-mode [2]).

what kind of managing do you do ? I dont spend more than 1 hour a week with my manager, so I am not sure where your time goes ?

From chicmath (https://www.ocf.berkeley.edu/~abhishek/chicmath.htm), Halmos' Finite dimensional vector spaces:

> But this book was where I first learned about tensor products, and why the matrix elements go the way they do and not the other way (Halmos is very careful on this point).

I haven't read the book, but it sounds like the answer may be there.
