What plugins would you say are mandatory for a fresh, SageTV server install?

[Sagetvmaster]

I'm doing some experimenting and was wondering what plugins people use for what reasons, are they mandatory, optional but useful, etc.
How I use Sage:
watching directly from the server, tuner sources being either OTA, cable tv set-top box and streaming devices (I use an Apple TV box plugged into Sage as in an input source).
Sometimes view remotely on either an iOS device like an iPad using Plex, Jellyfin or AirVideoHD, or via Android devices using the same apps or the media player from Josh.
Thanks in advance
