I have a StudioLive 32.4.2AI mixer and use both UC Surface on an Android tablet and Universal Control on a MacBook Air laptop to interact with it. Since I use this mixer with two different bands and therefore use a majority of the 32 channels, the color-coding and labeling is very helpful for me and other personnel to quickly apprehend relevant channels in the software. Both software products allow the setting of an icon for each channel to further give a quick visual indication of which channels are being used for which type of instruments. BUT, after spending time assigning these icons, they're lost/forgotten by the software when either application is restarted. Why? Why not allow those useful indicators to also be saved along with the color coding and naming? This seems like it'd be a modest but rather helpful enhancement to enact in these two applications. Requesting that you add that intelligence to the software.
[I've asked in the Support site whether this is a bug as it seems so to me, but the reply given was that the only possible way for this functionality to be realized is to ask here as a Feature Request.]
