Which has happened before and is the reason why the International Criminal Court is moving away from MS365 [0]

This prompted me to try OnlyOffice, and man is that nice. I do like LibreOffice, but 2 things bug me: It just looks old. And second, I have, since the dawn of time (and the Sun's Star Office) had issues just telling the software: "This is a Dutch doc, apply Dutch spelling and Grammar Checks". It has never worked well, even Firefox text fields work better. But with OnlyOffice it seems to work well so far, and also, it will be much much more recognizable by ex-MS Office users. It hear the interop with MS formats is also better.
