Catch it
A thought barges in. Press ⌘⇧Space, type it, hit enter. You're back in your work in about half a second.
It waits
The thought lands in your box. Nothing nags, nothing auto-deletes. It just waits, safely out of your head.
Look once a day
Open the box when you're ready, or let Kistle nudge you once a day at a time you pick. For each thought, decide: do it now, set it aside, or let it go. Take one on and it gets your full screen, with a quiet timer if you want one.
The loop closes
Finished things clear themselves after a week. No graveyard of old tasks, no guilt. Your head stays quiet.
