What I'd love to see is a way for me to write relatively vanilla HTML, possibly run it through a parser (in a perfect world, I would just annotate it with css classes) and out comes a sexy presentation. Or maybe a wysiwyg UI, like how Prezi's interface works.
Anything that is on a step is custom HTML and CSS and author is expected to write it. Stylesheet given is not meant to be a part of a library - it's just a demo.
I know that it narrows the target users to people knowing HTML and CSS (on a quite good level) but it's just an experiment and a tool I use. If anyone finds it nice and helpful that's great. If not - it's not my fault.
But for sure some detailed docs for impress.js are needed and I hope to write them soon.
It could work with some custom markdown tags like First sl[[i](transition=leftrotate target=second slide)]de
Personally, I dont have a presentation which I cant express through markdown.
Yoda is "hardcoded" because it's just a demo.
