[feature request] Ability to disable or reorder threads on a track

[Antymon]

My profiles tend to have lots of host threads but only a few of them seem insightful. Unfortunately, the insightful ones can be miles apart which makes it hard to analyze inter-thread correspondence of relevant ops. It would be great if we could collapse unwanted threads.

Thanks for suggesting this feature. We will schedule this feature for TF 2.5.
