About Flexinode, how to rearrange the order of "add" list

Hi.
It's about flexinode.
When you go to "content | content type" (and after creating a custom content type), you will see this "add" list:

add book_link
add color picker
add e-mail address
add image gallery
add MP3
add table
add URL
add date/time
add checkbox
add file
add image
add dropdown menu
add text area
add text field

I would like to rearrange the order.
Does anoyne know how to re-arrange the "add" list (eg make them alphabetically listed)?
Thanks.
