 Do you want to try some new experimental features? On the latest version of the Apple SDK, you can:
 
-- Enable <PlatformLink to="/tracing/instrumentation/automatic-instrumentation/#time-to-full-display">Time to Full Display (TTFD)</PlatformLink> to gain insight into how long it takes your view controller to launch and load all of its content.
 <PlatformSection notSupported={["apple.tvos", "apple.watchos", "apple.visionos"]}>
 - Enable <PlatformLink to="/profiling/#enable-launch-profiling">App Launch Profiling</PlatformLink> to get detailed profiles for your app launches.
 - Enable <PlatformLink to="/profiling/#continuous-profiling">Continuous Profiling</PlatformLink> to get full coverage of your app's execution.
 </PlatformSection>
+<PlatformSection notSupported={["apple.macos", "apple.watchos", "apple.visionos"]}>
+- Enable <PlatformLink to="/configuration/app-hangs/#app-hangs-v2">AppHangsV2</PlatformLink> to get more detailed app hangs. This differentiates between fully-blocking and non-fully-blocking app hangs, and also tells you the duration of app hangs.
+</PlatformSection>
 - If you use Swift concurrency, stitch together stack traces of your async code with the `swiftAsyncStacktraces` option. Note that you can enable this in your Objective-C project, but only async code written in Swift will be stitched together.
-- Enable <PlatformLink to="/configuration/app-hangs/#app-hangs-v2">AppHangsV2</PlatformLink> to get more detailed app hangs. The main difference is that AppHangsV2 differentiates between fully-blocking and non-fully-blocking app hangs and measures the duration of app hangs.

-    // ...
+- Enable the <PlatformLink to="/configuration/options/#enable-persisting-traces-when-crashing">`enablePersistingTracesWhenCrashing`</PlatformLink> option to link ongoing transactions to a crash event when your app crashes.
 
-    // Enable all experimental features
-    options.enableTimeToFullDisplayTracing = YES;
-    options.enableAppLaunchProfiling = YES;
-    options.swiftAsyncStacktraces = YES; // only applies to async code in Swift
