Is there any option to make the map scale match the canvas scale automatically? That is without having to use the "Set map scale to match main canvas scale" button.
Actually I expected it to be automatic by default and maybe have some button to stop this behavior and set the map scale to a fixed value. As this isn't how it works I guess there must be some other easy way of getting the automatic behavior but I haven't found it so far (no option, no switch button, no variable...). Is there anything I missed?
By the way I know python expressions could help but I'm looking for a built-in functionality.
