Note to reviewers

This is a work in progress, I am still unable to get slides exporting in the correct direction

[daughterOfSpring]

At this point I'm not really sure where to go, I can't seem to get the direction to be communicated from the nextSlide function to the revealjs code that builds the html. I'm sure I'm missing something, but I'm going to need to keep looking into this before its ready to merge.

At this point in addition the additions mentioned in my first post in this PR I have also:

• Added a loop to the revealjs.html script that creates additional section tags whenever it detects that the user is attempting to create vertical slides.

Hi @daughterOfSpring, thanks for your contribution! I think the confusion about your PR currently not working is related to the mystic behavior of the BaseSlideConfig.wrapper, see my comments below. I hope it helps!
Other than that, the PR looks great :)

Looks great @daughterOfSpring, thanks! To wrap up, could you add a entry to the changelog to document your change? It can go inside the # Added section.

I can but which release do I put it under?

[jeertmans]

You need to move this under the # Unreleased section, since your changes are not yet released :-)

Are these tests failing due to my changes?

Are these tests failing due to my changes?

No, don't worry, those tests are failing for unrelated reasons.

Could you check this #602 (comment)? After you move the changelog entry to the correct position, I think it can be merged :-)

Looks great, thank you so much for your contribution @daughterOfSpring!
