I'm new to the Quest 2.
Gonna use VRChat for my VR Legs (I'm now fine keeping the headset for more than one hour).

What apps would you recommend installing ?

Meta Quest Browser
Meta Quest Files
Meta Quest TV -> HereSphere (but no subtitles support), Bigscreen ?
YoutubeVR
Games/PCVR : AirLink

And here's what I'm currently using on my other Androids
Browser : Bromite
File brower : MiX
Media/NAS player : MiX or VLC (Kodi on TV) (+ ZeroTier for remote)
YouTube : NewPipe (SmartTubeNext on my AndroidTV)
Games : Dolphin / redream / Steam Link (for remote)
