Mix assign matrix/overview (similar to I/O matrix with full channel count) would be a useful feature to speedily assign/un-assign all channels to correct mixes/groups upon creating a show file. Would also particularly be useful on a Solo to check that any hidden channels are not passing audio (double patches) without intention.
(Sorry for all the posts, just finally used mine on shows the last few weeks, and got feedback from other engineers who’ve been on shows with me)
