I’m suggesting two small tweaks that I think would make this dialogue better.
First, it would be nice if “Only show lists that contain this term” showed finished lists as well as unfinished ones. That would make it much easier to see whether a term is already in any lists. The current behavior is limiting.
Second, it would be useful to be able to navigate to a list or schedule from this dialogue. Currently, the highlighted links are redundant to the checkboxes.
