Disable Markdown in preferences [feature-request]

If possible please add option to disable Markdown formatting completely in preferences.
It would be easier to make pure-text only notes.

e.g. I often uses pure txt lists of pros and cons like this:
- very easy to use
- resource free
- works one every webpage
- every plus (+) and minus (-) signs must be preceded with backslash () or will be converted to html lists
- every line must be ended with double spaces or it will be merged with previous line
- many non-common formatting glitches causing slowdown when taking notes

with Markdown formatting on there is much more formatting corrections (double clicks, backslashes, adding enters and double spaces, etc.)
