I would love it if you added two things:
- time limits within a larger time frame. For instance, setting a profile to be able to have access to the computer between 3pm - 7 pm. But during this time frame they are only allowed to do two hours worth of computer time.
- being able to set time limits within specific categories. For instance, of there four hours framework of computer access time, they are allowed to do 30 min. worth of games, and one hour worth of educational work, and 30 minutes of youtube.
For me these two features would make this perfect.
