Is MultiMarkdown Composer available in languages besides English?
I speak English. I speak very little German, and even less French. I can (sometimes) order food in Spanish. I used to be better at other languages, but am out of practice. I am trying to fix that (travel is fun!).
That said, I don't have the skill set to accurately translate MultiMarkdown Composer into other languages appropriately.
But I can make it so you can help. ;)
To learn more about the effort to localize Composer, see this page:
MultiMarkdown Composer 4 is set up to allow for standard macOS localization techniques. As I get help, I'll start implementing it in future releases.
