Kdissert is an awesome app behind a simple idea. Giving talks and product presentations, you realice how hard is to make non linear presentations. When the complexity of an idea is high, sometimes you cannot express it linearly.
Kdissert help you to simplify what you want to say. After you make clear your ideas, it generates automatically a latex beamer presentation. I'm still fighting against the template, but hey...I don't have to do it everything at once. For this presentation I'm working on, I've made some progresses. Hopefully, by the end of the year I will be able to make presentations a lot faster than right now, using latex beamer from scratch.
If you are tired of making complex presentations, this is a good approach: kdissert + latex beamer.
