Re: cluster fuck of a "Ribbon" UI
"I often use LibreOffice and its great, but rarely follows the document layout in .docx in my experience, better with .doc"
I've seen the opposite. I regularly get .doc files from others that don't look quite right. Especially if you get the "wrong" version of office. In any case, LibreOffice gets it mostly right enough to get the job done. Cross-version support for RTF is even worse.
I even have one associate who distributs everything in .doc format, because (his words) "PDF doesn't display properly". He doesn't see the irony when I call and ask what version of word he used just so I can bloody see it properly.
