Toggle features that generate extra HTML

[davidrutland]

Is your feature request related to a problem? Please describe. Notes generates extra HTML such as:

<pre data-pm-slice="1 1 []"> ...when I'm expecting just <pre>

or

<H2 id="...."> instead of <H2> This can cause problems when copying directly from Notes to a certain fragile third party CMS.

Describe the solution you'd like

Toggles for extra features such as Data slice, ToC etc

Describe alternatives you've considered

Manually stripping out the extra HTML - which is a pain when I have to do it a few times every day
