My ideal use case for this is have a separate channel view that shows me any broken marks in my cues (Flexi Broken Marks). It’s easy to miss them sometimes, and it would be helpful to have so I could quickly see which channels are broken without having to do a query in every cue. Could also be helpful to see what is marking with a Flexi Marking or what is marked with a Flexi Mark, or maybe a Flexi Live Moves or Flexi Dark Moves.
Not all of the query options would be helpful, but I could definitely see myself using all of the ones mentioned to make my life easier and a bit faster.
