The Critters section has two new improvements. Thanks to Daniel Zimmerman for suggesting both of these.
First, there's now a Type filter menu. You can use this to view only Bugs, Fish, or Sea Creatures.
Second, each critter has a new Made checkbox that you can use to record critters for which you've made a model. If you have the Sync feature enabled, these Made checkboxes will be synchronized along with the rest of your data. There's also a new Made filter menu so you can see which critters you've made or haven't made.
Enjoy!
