tufte-latex VS LaTeX-KOMA-template

You might want to check an Edward Tufte - inspired LaTex class: https://tufte-latex.github.io/tufte-latex/

in previous posts in this subreddit i got rec'ed this https://github.com/Tufte-LaTeX/tufte-latex however im struggling to get started with creating documents with it, not really understanding how it works to get the document classs set up etc. so can anyone give me some help, once i get the first steps it will probably be easier then

--- PS: I know that that tufte-latex already exists, but I really wanted to try to create the perfect thing for me, while learning a lot about LaTeX.

The thesis style is based on https://github.com/Tufte-LaTeX/tufte-latex. My preamble is a mess but if you email me I can send you a copy. :D

As far as I see on my LaTeX template of https://github.com/novoid/LaTeX-KOMA-template (which uses the KOMA package that provides better typography in any case), the horizontal space is not wider after dots.

I used a template for my bachelors thesis, made specifically for my university, but it is more or less usable everywhere: https://github.com/novoid/LaTeX-KOMA-template

Mediocre: most companies I worked for had a Word template which had either technical issues or typographic/styling issues or both. I'd be surprised if your company is different. As a matter of fact, most LaTeX templates are quite fine in contrast even when they aren't as sophisticated as mine. So much for professionalism of template design. SCNR. YMMV.
