Here are some elisp libraries, links & docs that i have collected or written to improve the capabilities of GNU/Emacs.
You can also look at my .emacs (updated on Jan 10 2017)[html] and .gnus (updated on Dec, 27 2008)[html] configuration files (warning : W.I.P ;).
Thanks to Matthieu Moy for his htmllist.sh script that helped me to make this page (local copy).
