dark theme

The default markdown theme is grey, I prefer dark theme so this is how to change it.
Preferences/Package settings/Markdown Editing/Markdown (Standard).sublime-settings, add line

{
    "color_scheme": "Packages/MarkdownEditing/MarkdownEditor-Dark.tmTheme"
}

you can find "Markdown (Standard).sublime-settings" in sublimetext3\Data\Packages\User or ~/.config/sublime-text-3/Packages/User.
