Here's all my suggestions propped into one post, I have too many to bump at once.

Chat message pop-up.
Summary: Whenever you post a lion for stud, you get a pop-up asking if you're sure you posted it in the wrong chat. (Outside of sales)

Fire escape adjustments.
Summary: The visual art of August's "Fire Escape" gets tweaked for better display. Many players say it makes them dizzy.

August base suggestion: Husk.
Summary: (Semi) Natural breeders would love this creamy muted base!

Outlaw Clickbait trades.
Summary: Some players use a clickbait tactic to gain attention in the trading center.

Deleted accounts and branch listings.
Summary: Alot of deleted accounts have branch listings, resulting in clutter. These accounts cant update the prices/listings on their own, so my proposal is that these should be deleted.

Better moderator rewards.
Summary: Mods are understaffed, underpaid and underappreciated. Let's implement better rewards for more attention to the position, more dedication and a better community!
