For now, after using backslash command (coupler) or once rendering a card, I cannot use undo/redo (Ctrl+z) to my previous sentences.
I want to use undo/redo after rendering a card if I don’t refresh or move the page (that is, if the card keeps visible on the screen). Also, after using coupler or pasting (Ctrl+v), I cannot undo! This seems to be a bug.
I’m sorry for bothering you if this is a duplicated topic!
