Why another editor?
With so many great markdown editors out there, the question remains why another one is necessary. I am a political theorist and therefore need to read a huge amount of texts as well as keep notes for each and every one. This makes it necessary that I keep all of my files as open as possible and also searchable.
Additionally, I tend to write my papers using as little markup and styles as possible. Word processors as Microsoft Word or LibreOffice are simply not made for easy and focused writing. That's why there is Markdown. It keeps apart your content and your final styling of a text. This way you are not distracted by all the neat formatting options word processors offer you and focus only on your content. Styling is applied in a second step.
Zettlr solves all of these problems in one single app. With Zettlr I can write in one file, simultaneously copy text from other files and finally export my papers using the powerful open source platforms pandoc and LaTeX. Simply put: Zettlr is the get-together of the best features of existing solutions and a supercharged approach to your own workflow!
