The traces view now has filtering and sorting built in. When you're hunting down a runaway agent or a prompt that quietly ballooned, you no longer have to scroll.
Sort by cost — Order any trace list by total cost, descending. The most expensive runs float to the top of the page so you can jump straight to the worst offenders.
Sort by tokens — Same idea for token consumption. Sort by input, output, or total tokens to find the prompts that are eating your context window.
It plays nicely with the existing date-range, label, and metadata filters — stack them to scope a cost investigation to a single feature, customer, or environment.
