In reply to Kourosh.

Hey Kourosh, nice to see you here! :)

I have "Clean up Inbox items" as a project because, in my current system, an action is unprocessed if it's untagged (except on-hold lists where I keep someday/maybe items).

I assume "both project and a tag" would be the logical answer, but then OmniFocus will not group items by project until I assign a tag. I could try that, but it seems a bit more work.

It would be nice to keep everything in the Inbox and sort it by the project. Maybe I can create an automation plugin that does this.
