Show single sided cards as “other” in secondary count just like double sided cards. Example - Dryad Arbor is included in lands but not counted as a creature.
Came here to suggest the same thing after noticing that Prepared creatures are counted as “other” Instants and Sorceries. This would be very helpful for Artifact or Enchantment decks so they can quickly see their Artifact Creatures, Enchantment Creatures, or even Enchantment Artifacts.
As a side note, this may be a bit more complicated, but noting cards with Changeling when sorting by SubType may help as well.
