Tried this out. Loved it. Now we just need tabbed Microsoft office. I've been using WPS Office for quite a while now, which is a (mostly free) alternative that is superior for having one simple feature: it has tabs, each tab can be a word document, spreadsheet, slideshow, or their (admittedly imperfect and also subscription-based) pdf editor. It has every feature of ms office that I've needed so far, though it is undoubtedly inferior in feature set, doesn't appear to play very well with OneDrive, nor can you use ctrl + number key to jump to a specific tab, so I'd jump ship back to Microsoft office very quickly if they added tabs (I in fact have a Microsoft 365 subscription, but I still use WPS because tabs are just too important to me, sometimes I have to work on over a dozen files at once and without tabs I'd be alt+tabbing for years).
