I’ve made a few new filtered decks in Anki.  Most of them I don’t even study, but they help me keep track of my progress:

The first filtered deck I do actually study from.  This deck vacuums all of the cards from various decks that are due today into one deck. The code is simply is:due  This is convenient, but it’s not the main reason I made this deck.  At the beginning of the day, I rebuild this deck and I can immediately add and study a few new cards.  That way, I can learn new cards first thing in the morning instead of waiting until I’ve studied all my reviews which is sometimes after lunch.  I feel I’m a little more likely to remember new cards the next morning after absorbing them over a full day.

The other decks vacuum up specific types of cards to give me an easy count of them.  I have one each for vocabulary, kanji, and sentences.  They all go something like this ("kanji deck 1" "kanji deck 2") -is:suspended prop:reps>=1  *Note that the iphone app has a bug where >0 produces zero results so you have to use >=1.
