Not sure if this is being used at all and therefore if its on the roadmap for any improvement but whilst testing it I thought it was a shame that it cannot be customized or personalized in any way. Lets be frank, it does not bring much & I would rather access the data in full on SC not through such a small window but this is because I have access to SC. On the other hands, I have colleagues who use iGoogle at work and rather heavily, but then they don't have access to SC. It would be much better if a reportlet could be converted as an iGoogle or any other vendors' types.
