The freely available, opensource SelfControl app is used to block access to websites for a defined period of time. [url removed, login to view]
I would like you to either modify SelfControl or create a separate small app that overrides SelfControl for the following purpose:
I would like to block certain hosts (eg. [url removed, login to view]) 24 hours per day but allow myself to override the block for up to 30 minutes total per day.
The interface should show a count down of time remaining for the day, as well as a start/stop button that, when activated, overrides the SelfControl block.
