@valentine tomin I reckon the best thing to do is just link to a cloud document (Dropbox Paper, Word, Google) from the card and then people click through to edit it. There was some other note power up that I can't remember the name of that loads the document in a dialog/popup on the same screen as Trello, but naturally that would only work on Desktop so to my mind just having a link to the cloud version of the document is a superior choice anyway.
