The essential SteamVR app.
But it has issues that need fixed.
If you have more than 7-8+ watchman devices (2 controllers + 8 trackers) in use, the hotbar for battery visibility gets cut off so you just kinda have to guess what the rest's battery percent are at.
Panel Min/Max fps should be able to be enterable via keyboard as moving the slider with shaky hands to the value you want is frustrating.
I wish there were more options regarding performance metrics like selecting a GPU to monitor, display all cpu threads. GPU monitoring seems inaccurate as well as the frame-time counter if you are running full-speed, unless it's showing overhead but that should be a separate metric, not tied to the same counter.
