Sometimes I split preamps to different channels, and sometimes its hard to fit both a distription of the source and the use in the channel-label.
Ergo, it would be nice in the preamp-menu to be able to write a short comment or description. i.e.
Channelname: Lead Vocal
Comment: IEM Dry vocal for band monitoring
This way if you created the mix months ago you wont have to open the i/o or try to remember color-coding to find out what the use of a specific channel is.
Right next to the stereo Image and below socket preamp in the preamp window for example?
