LaTeX Template
Working with LaTeX is great. Working with outdated templates, or combining 10 different templates that are all nice but all lack some specific feature that you are looking for... not so great. During my master's I saw that every year many students were solving the same LaTeX issues when writing their thesis. I had wanted to design my own LaTeX class for a long time, so I figured, why not go all the way, save everyone alot of time and trouble, and create a template that all students can use. Fast forward a year (this was not a fulltime effort), and it became the Leiden Observatory thesis template!
You can find it in the Overleaf template gallery, or download it from my GitHub.
