Hi @kkphoto. There's two features in there you're really asking for:
1) Duration based time limits (e.g. 1 hour of gaming, I don't care when)
2) Category based time limits (e.g. gaming from 4-6pm only, but other categories 4pm-8pm).
The current version does not support either scenario easily, but #2 is probably our most requested feature and will be available in the coming months (no date yet).
To work around it in the meantime, you could manually toggle the games category on and off for the hour you like.
You can set up multiple profiles, but a device only lives in one profile at a time. If you move it into one, it moves out of the other. (it also takes a few minutes for all the settings to become effective if you move devices around). So, I don't think that's really the solution for you.
Thanks for the compliment... we especially love when the compliments make it on to amazon
