Ok, it has “ever” been there, but I found back to it. I used it once to write my diploma thesis and was impressed how easy it is, to write long texts with it. It is not really easy for people who are used to Wysiwyg software like OpenOffice or so, I think. But for software development oriented people, it is really easy. And the output is much more professional than with any Wysiwyg tool.
Until now I used LibreOffice to write the documentation for efaLive. Now I switched to LaTeX and am very happy about this decision. The handling of the document is much easier, you have better control of the layout and you just need a tiny editor. To convert the LibreOffice document, I used the writer2latex extension for OpenOffice/LibreOffice. I used the ultra clean setting for the export.
I should always use LaTeX for long texts!
