This might be the exact issue I was just working through, but in the opposite direction. We’d like to be able to filter out any task that’s currently blocked by any other task. but it looks like Blocked By requires a specific task ID. Kinda odd, as I don’t imagine it’s common to want to filter for all tasks blocked by a specific other task.
For more context, we’d like to use this as a workaround until Feature request: Explicit template lists is solved. We have the first task in our templates entitled Make a copy of this list, which all of the other tasks are blocked on. If we could filter out blocked tasks, this would allow us to reduce the noise created by all of the hundreds of template tasks showing up in our personal assigned-to-me lists.
