@Brendanjones My first question these days for a new collaboration tool, more than what features it currently has, is: what's their attitude to inter-op? Is it like, "obviously we include a chat feature, our own little chat silo which we invented here, and obviously we provide a server for you to share drawings, our own little silo server"? Or is it like, "obviously we make it easy to plumb in to your own matrix chat rooms, and obviously we make it easy to plug in to your open file sharing protocol (WebDav, NextCloud) for sharing your drawings"?
