Yes, I do use Hangs instrument and I find it very useful, and I'm usually lowering the threshold to 33ms in Options. But still, I think it would be useful to use something like 100ms threshold on-device while testers are testing the application, because not all of the developers are used to profiling the application, and it would be more convenient to find hangs while testing. I'll fill out the enhancement request, thank you!

This actually works, thank you!

12.4 was the last version of Xcode where syntax highlighting worked fine for me. Installing all the new betas hoping they fix it, but still disappointing ;(
