some features

[sokra]

Hi

i have used impress.js for a presentation and added some features. I like to contribute these to the official project, but i have not used github until now. I was able to add the features in my own fork.

The main features added are: Nested steps and Templates. See my readme for more details.

Also see examle at: http://sokra.github.com/impress.js

I would be happy if i could contribute to this great project.

Wow.

Too many features at once :)

Interesting work with nested steps (there were some other guys asking about it in issue #9).

And for the others, I'm not really sure how useful they are:

• The phi/r coordinates - who will possibly use it? :) I think the whole x,y,z plus rotations around all axis are complicated enough for normal human being :)
• These 'templates' ... the effects are indeed quite interesting but the whole thing is way to complicated. Effects like these (but quite simpler) can be easily achieved with CSS transforms based on active class on current step.

Basically, the whole code got so complicated I can't understand most of it anymore :)

Thanks for your input. I want to keep impress.js as simple as possible. Your work is quite inspiring, so I may get back to it at some point and see if it fits to my vision of impress. But right now I'd like to focus on core functionality.

Thanks!
