Defining a css global file for markdown like on the Mac

Is there a way of defining a global css file for markdown presentation like in the Mac?

Does DTTG v3 have this facility?

Not in the settings, no. The only possibility I’m aware of is adding a link to the CSS file to every MD file. Which is not really a solution in the proper sense of the word, I think.

@chrillek thanks.

Just purchased v3, hopping that this feature will be added.

It is not in DTTG 3
