Here's how my Inbox is set up now:
- First I have all items with "Calendar" label - I set up a rule to have all the auto-reminders from Google's Calendar directed automatically to that label without staying in my Inbox more that an instant. This is a tiny list as I delete anything's that in the past.
- Next I have my starred list - this should be kept under 10 items at all times. If I go over 10 it means I must kick something off it by taking care of it immediately.
- Then comes the unread list - this is currently still too long but I'm working on trimming it. I've already filed away quite a lot of the unread clutter using labels and deleted a lot too. I'm hoping to get it under 10 at all times as well.
- Last is the rest of my inbox.
