Thank you for that; I recently tried to find out how he implemented his 30 second distraction-delay but I had misattributed the quote and so my search was unsuccessful. I think that the delay is a powerful idea.

The approach I'm experimenting with is a "productivity mode" toggle in a tiling windows manager which disables most of the windows manager commands, leaving me mostly stuck in whatever application(s) were already visible until I toggle it off. The toggle off function has a 30 second delay.
