Writing structured text documents

I recently bought an Android tablet with a keyboard, and would like to use it to take notes of conferences, lectures, meetings etc. On a Windows or Linux notebook, I would use the excellent LyX system for this. LyX basically allows you to write structured text without worrying about the layout, saying "this is a #3 heading" or "this should be emphasized" instead of "this should be bold and a larger size". LyX then allows you to export your text as PDF, DOC, ODF, LaTeX and so on. I am looking for an App that allows a similar approach to writing for Android. What I already tested: - Writer is almost what I'm searching, a minimalist text editor that understands Markdown and saves its document as plain text on the Android device (no network necessary). I'd like a few more formatting options and an export feature, though. - Write:Tablet doesn't seem to have many structuring features - Most "office" packages like Polaris Office do not offer format templates, but restrict the user to bold / italic / font size types of formatting - Google Docs needs a constant net connection So, I'm aware that this is a very small niche I am looking for here, and such an app would probably not make sense on phones, but is there another interesting tool for structured text creation?
