I'm using data tracks to control Qlab and open and close the shutter on our Panasonic projectors. Although I have successfully used Millumin once to use Art Net sends to the projectors every other time it seems to blast multiple commands and ends up turning off the projectors instead. I now have a simple 3 cue Qlab session that 'just works' so am leaving that open in the background and sending midi from Millumin.
To help problem solve though it would be good to be able to enable/disable data tracks on the dashboard so you don't have to delete (and thus reprogram) tracks.
It seems the best way to really do this currently is using timelines with just a data track in it. On this same note if you could set presets for Data information - so if 255 is sent via art net I can set a preset on a drop down saying 'shutter open' and then another at 0 for 'shutter closed'. No need to memorise which is which (kinda like segments on timelines - but in the data area).
Oh and one last request - collapsable data track area please!
