channels

the "Channels" dialog allows manipulation of the song's channels.

each channel has the following options:

Visible: uncheck the box to hide the channel from the pattern view. pattern data will be kept.
crossed-arrows button: click and drag to rearrange pattern data throughout the song.
- note: this does not move channels around! it only moves the channel's pattern data.
Name: the name displayed at the top of each channel in the pattern view.
the next setting is "short name", which is displayed in the orders view and/or when a channel is collapsed.
