A gauge chart/widget would be a nice addition. This seems to be standard in most reporting dashboards across the net. Ninjacat needs one too. Remember, need a max and ability to indicate certain areas on the gauge that mark for instance the 50% or 75% marks (customizable). Think of it as green zone, yellow zone, and red zone.
Also, it could work as getting a metric between 75% and 100% of the max number is green zone (a set target if you will at clicks or sessions, something good). This could be reversed in also saying red zone if this area reached (for instance cost).
