@Jo Astley, where an new issue goes is entirely dependent on how the author of the board defines the order by using the ORDER BY function in the filter that defines the board. You mention that highest priority should be at the top. That may be true in your case but not necessarily for everyone. Also consider does the newest highest priority come first or does the oldest highest priority come first? Regardless, as mentioned initially, you have the ability to define ordering.
I don’t know of any such setting.
