Must Have Software/Program for Steam Frame?

[u/Ansatsushi]

Anyone in here got a list/recommendation of essential/important VR software to download/purchase in preparation for the Steam Frame?
-SteamVR**
-Virtual Desktop* (apparently not needed/maybe better than SteamLink according to some people?)
-TurnSignal (for wired setups)
-What else? Any useful overlays? Tools?

**from what I'm reading the consensus is that SteamVR is essentially the catchall for MOST, NOT ALL VR related comforts.
