I appreciate programs like Obsidian that automatically saves my work, yet let me press Cmd+S without saying anything. It’s empathetic of those trained to frequently Cmd+S whenever they’re working on something. It may seem like showing a message saying “you don’t need to save” is useful, and it might be first time for new users. But doing it every time they press Cm+S quickly becomes distracting. It takes a long time for this reflex to be unlearned, especially when there are programs which still require explicit saving. So just do nothing and say nothing. Let the user press Cmd+S in peace.
