Make flymd accept other file extensions

Question

When I try to preview my markdown files I get this aggressive funny response:

What’s wrong with you???! Don’t flyit if you are not viewing a markdown file.

But I am! ;-) It's just that I use .txt as extension for them. I'm even in markdown-mode.

Could I tell flymd that it's ok to try and preview these files?

Answer 1

Based on the source of flymd, you need to add \.txt\' to the option flymd-markdown-file-type as well, using M-x customize-option.
