I've mentioned this before, and I hope it's being considered for application. Solo Groups. Instead of just having solo "pages" where all buttons within that page solo, how about some way of soloing just a select group of buttons within a page? This is not a Macro. I understand how those work and use them extensively. What I'm describing is a select set of buttons grouped so that only one can be on at a time. Currently, this can only be done per page, but that's often not an efficient use of a solo function.
For example, I use one page to control the separate brightness of several different fixtures. For each fixture group, I have buttons for On, Dim (fader button), and Off. I'd like those 3 buttons to solo, but I don't want to waste a whole solo page just for 3 buttons. If there was a way to "Solo Group" just those 3 buttons, it would very useful as the buttons within that group would self-cancel when another button in the group is chosen. Maybe a menu option that allows one of 10 solo groups to be chosen, then a corresponding small indication of the chosen group showing on the buttons (maybe a small 0,1,2,...,8, or 9 in one of the button's corners). This way, solo can be used more across the screen and WAY more efficiently.
