The APP has all the key elements for control, but it would be nice to control those elements more efficiently. For example I would love it if I could build a PROFILE (UI/Layer) for each musician's monitor mix. In essence, all the instrument channels and MASTER limited to ja specified MIX BUS.
Then have a Profile Menu to your startup screen where the user can select the appropriate profile (password optional) and it would load that configuration.
