Streaming movies. Allowed.
- At what level? G /Pg/pg13/ R/ E/ T / M?
- For how long? 30 /60 / 90 min etc.
- Between what hours? Between 6am-730am & 230pm-415pm.
- On what days?
So the custom look can be G/E movies on M-Fr between 8am & 3pm for 30 minutes.
And any time you want to bypass the set rule, you type in your password and allow 1.5 hours of a PG movie.
Every single feature is like that.
