for now the Django module will default sort the module in alphabet order, and show in the admin portal navigation bar.
Eg: Module A, Module B, Module C. will by sort to A, B, C.
there are some ways to change the order, eg trick the verbose_name of module, to manipulate the order, but it is not straight forward, and difficult to maintain.
I check the code, it is happen in get_app_list function, which by default sort by model name.
so thinking can we have a bool flag in setting file eg: MENU_ALPHABET_ORDER.
if it is True, will be same behaviour as before.
if it is False, the order will be based on the order when it registered to the admin. (the dict is default ordered since python3.6), so can just change the register sequence, will help to sort the menu accordingly.
Just an idea, not sure whether a good solution
