dnd-kit library
Challening parts
Documentation of dnd-kit library was outdated, some imports were not going through as modules from the docs did not exits.
Things I learned here
Unrelated, but to use multiple cursors in VS Code. I forgot the shortcut once again. It is ctrl + alt + arrow down on Windows. And the hold ctrl and press right arrow if you want to get to the end of each line and start typing there.
