This is one of the things that drives me crazy. If you add a new fixture type to the patch, and that new fixture type has parameters that are new to the show, those new parameters are not enabled in Live Table tabs. I have several snapshots with a Live Table tab that all now need to be either (a) updated one at a time, for every possible state because Blind Cue and Blind Target display different parameter sets, or (b) deleted and resaved, also one at a time.
It would be fantastic to either have new parameters get enabled by default and/or be able to adjust what parameters are shown in a more global fashion.
