How to re-order menu position on the Admin page?

Hi, I need to change the position of menu on the Admin page. Anyone can help me? Thanks so much!
tim
Edit includes/templates/default.admin/layouts/default.inc.php
Example, I have left menu in Admin panel:
1. Left menu 1
2. Left menu 2
3. Left menu 3

So how can I reorder their position to:
2. Left menu 2
1. Left menu 1
3. Left menu 3

And I am not a developer. Thanks.

Each and every app can have a priority value in it's config file that is taken into consideration when sorting. Other than that you can write your own sorting function to sort the apps before outputting them. See the php manual for usort().
Hi tim, I do not see the priority value as you guide.

Can you show me that? I have a copy of my screenshot for example.
