Implement nested list items

[purrutia]

Is your feature request related to a problem? Please describe. On a presentation I would like to add a contents slide. In markdown, I usually use nested lists on a markdown file with tabs, for example:

1. Item 1
2. Item 2
   1. Sub Item 1
   2. Sub Item 2
3. Item 3

But if I do that on slides the result is:

1. Item1
2. Item 2
3. Sub Item 1
4. Sub Item 2
5. Item 3

Describe the solution you'd like I would like to have nested lists like:

1. Item 1
2. Item 2
   1. Sub Item 1
   2. Sub Item 2
3. Item 3

Describe alternatives you've considered Use lookatme instead (works there)

Like that? According to Markdown standard indentation with 4 spaces are required to achieve that. I've tested it in slides version

1. First item
2. Second item
   2.1 First sub item
   2.2 Second sub item
3. Third Item
