I find whitespace-mode invaluable in finding trailing whitespace, use of literal tabs and the like I always have it on when looking at code. Good tips in the article but I wish it had screen shots / showed examples.

For trailing whitespace, isn't simply the variable show-trailing-whitespace enough?

I'm discovering about whitespace-mode and found this article which helped me to understand the package. Do you know if it allows to display TAB with a specific background colour?

Emfy setup recommends three settings for trailing whitespace:

(setq-default show-trailing-whitespace t)
(setq-default indicate-empty-lines t)
(setq-default indicate-buffer-boundaries 'left)
