I am searching for an application (Desktop- or Web-App) to write and create interactive documentation (especially technical documentation). I like Madcap Flare for technical writing, but I'm looking for something that can also create dynamic media - fulltext search, slideshows, expandables, and similar.
It should be easy to adapt and easy to integrate in other processes. And the important thing is that it needs to have a responsive HTML5 output.
If you are reading this and maybe working in the technical documentation sector, what program/app would you use for it?
