UX Polish: Markdown docs are opaque

I don’t quite understand why markdown docs can’t be a resizable card just like a text element on the board. Obsidian, Heptabase and some others provide a fold/unfold icon so people can choose if they want the text visible or not for each document.

I would rather write markdown on the board itself like a text element than be taken out of context unless I specifically want to open the document in a fullscreen view and I do that through a command. Taking people out of context should only be done with good reason and should generally not be the default.

It would be helpful to have some options in this regard rather than assume that we all want the text of our markdown docs hidden all the time.
