You may wish to change the order in which the channels are listed in the gallery. This is done by numbering the channel Shortname. Note that the Shortname is a system name, and does not appear on the front end of the player. If you don't number the short name channels will be sorted alphabetically by Shortname
Note that you can sort the list from the channel page by clicking the column header. You will notice that the channel structure stays in tact, and that you can further sort sub-channels in the same way.
