Allow setting "Hot" as default topic list for categories

Not disagreeing that it is complicated, but this isn’t Hot’s fault. :slight_smile: In fact, Hot brings simplicity to those who aren’t quite satisfied with Latest and Top. What about this implementation as an incremental step:

  • When the user selects “Hot” in Default Topic List, then Default Top Period and Topic List Sort By are greyed out because they are not relevant to Hot. Default List Filter remains as a setting, since it is relevant to Hot as well.
  • If the user deselects Hot, then Default Top Period and Topic List Sort By are selectable again, keeping the value they had before Hot was selected.
