This is a huge set of pedantic changes, none them affecting actual code.
Mostly, I tried to:
- use consistent names; e.g, use LaTeX wherever possible, not latex;
- fix broken symbol links;
- use capitalized comments with full stops.
Latex language module with previews, latexmk, reftex, bibtex and others.
Completion with company mode.
Selection of bibliography using Ivy or Helm.
Later preview panel or okular as viewers.
LatexMk for compiling code.
Prettified indentation with adaptive-wrap along with good indentation of environments.
Additional fontification of common commands.
