In-browser markdown editor [using vanilla JS]

I took a long time to complete this challenge and had loads of bug fixes but I am still glad that I finished it. I am building this as a front-end app first. There are still some more bugs to be fixed which I will come back to fix in the future.

The hardest part was the naming of the file when you add a new untitled document and making sure that the data/content between the live editor, localStorage, and HTML values all synced together.

Most of the features are working, at least on my side, with the only exception that the movement of the side nav bar isn't smooth. I love to hear from anyone that has a solution to that.
