I love google spread sheets, I also use them to track pod/pollen parents of the flowers I breed. I even have one for scape, bud, and fan count. (fan count mainly for irises.) Fan count of daylilies can be a bit tricky once the clumps get big.
I still have to add the iris crosses I made this year on the spread sheet. Not to mention I'll have to wait until a month or two after they sprout to add them though.
