Yes, I also use Zettlr and it works fine. Especially with the Zotero integration. But you are right, it sometimes needs some tweaks to work fine.

I do both, but usually I use markdown to write the texts because it features basic formatting like headers and bold text, but it’s faster and easier to write. Then I use pandoc to convert it into .tex and do the final editing and adjusting directly in Latex.
