I really like this plugin, especially how you treat how the post content is saved.
Unfortunately, there are some basic missing aspects that don't convert Markdown to HTML:
- Writing four spaces before text does not mark it as code
- Writing 1. to start a list, followed in the next item with * does not continue with an ordered list
- Blockquote is not produced by beginning the line with a "less than" character.
Thanks for the you you have done.
