This is my current messaging menu layout in Ubuntu 12.10:
I was wondering is there a way to change the list? I would rather have Thunderbird moved to the bottom. I tried uninstalling Thunderbird, which removed it from the list, but when I reinstalled it Thunderbird went back into that position. It seems the layout is set as you set-up the applications the first time which made me think there is something somewhere which defines how they are ordered in the list.
Any help would be great!
