I know I can add and delete post icons, but how would I go about re-arranging them (say if I want certain icons to be listed first, second, third, etc)?

same also applies to avatars and smilies - they all need some sort of ordering....

I think they should be ordered alpha-numerically -- that way we can sort them by changing the filenames...

It used to be that way I think - I seem to remember putting an x in front of the default avatars

I was able to re-order the Graemlins, because I found the table they are in and just re-arranged them in that table, but I can't figure out where they are located for the "post" icons.
