Align title to the left in markdown

Hi,

Concerning the markdown preview, I see that the titles are centered. I would like to have them on the left instead. How can I achieve this?

Best regards

I use widescreen monitor and it looks really weird when all the text is aligns to left side of the panel but the header is in center.
I know that resizing the window should do the work, but it would be nice as an option

I'm just reading the code, but I'm pretty sure it comes from here where it appears to be hard-coded
