Donators perk only.

The developer changed how auto-sorting works with chests, Trapped chests no longer auto-sort, giving pirates an easy way to disable sorting for specific chests (or even all your chests, if you’re concerned about other players sorting them on open).

Reminder

A lot of donators are unaware they can /depositall in their chest rooms to quickly deposit their backpack into chests, all organized! (I’ll add this to the guide page now)

/DepositAll finds nearby chests you can access and instantly deposits items from your backpack matching the items in each chest! (Doesn’t disturb your hotbar).

Future Updates

I asked the developer for a way to toggle the shift + right-clicking chests as I know it drives people crazy they cannot put blocks on top of chests as it auto deposits into them, waiting on his response.
