Not so easy to out-Google Google, is it? Though given the horrendous pile of dogshow that MSOffice code is*, it is surprising that they even managed to finally make an online version. Even late and incomplete as it is. They might have succeeded by rewriting the stuff from the ground up, but that's not the MS way is it? (last attempt at rewriting stuff was the aborted Longhorn, which eponymous keratinized integuments are still hurting MS collective backside 4 years later, I reckon).
Shorthorned BG for obvious keratinized integument reasons.
* MSOffice? There is no such thing. At least not in the "integrated suite" meaning that people tend to see in it. There are individual apps held together -barely- with a couple rolls of duct tape. That's probably why the available features differ from app to app in these online versions.
