Taking up a point made by GeekLady in another thread, I would suggest that the Inbox should be slightly reconceived.

We mainly think of it, for historical reasons, as a point of arrival but it would function better (without losing its original role) simply as a list of all incomplete records, (i.e. records lacking either a context or a project or both) regardless of where they were first entered.

1. Actions entered directly under a project or a context would show up in the inbox, as well as being displayed where they were entered, as long as they lacked either context or project (where "project" includes the status of singleton).

2. "Clean up" would allow incomplete actions to be displayed under the relevant project or context, but would not delete them from the inbox until they had both project and context.

This would not constrain liberty, but it would make the "Inbox" into a more predictable and rigorous checklist of meta-work to be attended to.
