I’m finding the same thing. There are some exceptions, e.g., tables which are harder in md but I’m finding simplifying is helpful and saves a lot of time. I spent many hours recently converting an entire graduate course–syllabus, standards assignments, you name it … into md files.
One thing that helped me was that I indexed the graduate course folders into DT and then did a mass conversation where possible to md. That saved a lot of effort!
A Word of Caution: I copied and pasted those original files into a separate folder for this work to protect the original just in case … this is always good practice when doing wholesale changes. I had also made two backups.
