Dear Saša Janiška,

I’d like tell you about my case.
I have used Beamer long time ago, but now I am using ConTeXt + Simpleslides module for my presentations.
There are already many given templates. 
You can find them in the doc of simple slides.(…../tex/texmf-modules/doc/…)
However we  can make our own template if we want. 
Although I am not an expert, I made my own template by modifying the given templates.

I think that ‘animation module’ is also a good module for presentation.
Using it, we can make the presentation more interesting.

I hope that you got what you want by using ConTeXt.

Best regards, 

Dalyoung
