I just noticed there is a new way the cells are defined.
The only drawback is naming of cells can’t be done easily. As I would have to make the cell as JavaScript cell and the use something like.
my_info = md '# markdown info'
Apart from that I like it as it makes the notebook more notebook like and less an online code editor (due to every cell being a coding cell).
The markdown js code highlighting isn’t as nice as the cells JS code highlight.
This is Great !
and i agree with @hellonearthis because the naming of the cell is very usefull especially when download the code and use those name to render or not a cell in the final page … (so for now i keep preciously all my cell as js cell …)
