Please add ES6 and JSX support.
Now it looks like:

And this is Babel highlighting:

sure, I can add this next time I have a chance to make edits. or would you like to do a pr?

[osenvosem]

@jonschlinkert I would like to with pleasure, if I had enough skills for that.
Btw, I asked you to add twig support on the 12th of May. Today is the 12th of October. Such a coincidence.

@jonschlinkert I'd love to help out this since currently the color just breaks for JSX elements, making it very ugly and weird.

For what I can tell, I should modify some places from these code block sections:
https://github.com/jonschlinkert/sublime-markdown-extended/blob/master/Syntaxes/Markdown%20Extended.sublime-syntax#L265-L279

and to change syntax highlighter to use babel. Am I correct?

@tomchentw did you fork this with any luck?

[jonschlinkert]

I should have closed this before. the "strange coloring" is from changes in ST3, some of which seem unfixable at this level.

@tomchentw @nathanmarks fork the hell out of it. this is open source, I do this in my spare time. I'm glad people get value of the package, but every time someone makes a comment like that it makes me want to make all of my repos private.
