The concept that's MAGICAL in Reveal.js is vertical slides.
e.g. https://revealjs.com/#/2/1 <-- from here you can go up or down, then go right to continue the presentation.
You just make one slide deck with lightweight high-abstraction slides and depending on the audience you just... hit the down arrow. bam. now you're inside the tech slides. no nerdy tech guys? sweet, don't hit down on slide 3. Instead you're with the marketing guys, so hit down on slide 5.
Anyway - looks like you got rid of that in order to mimic Powerpoint, but... don't forget it's there. it's my favorite part of using Reveal.js!
