I’m talking compatibility of displaing documents more than anything else, since even different versions of Word display the same document differently sometimes.

But the closest worlflow would be nice. Preferably something like '03 MS Word Office. It was crude in many ways, but I just hate ribbon menus and love having anything at hand. Especially a style menu, customisable keybinds and batch-replace with regexps.

Is there’s something to get closer to that in FOSS, or just Linux-compatible apps?
